Statistics about PerlMonks

on Dec 08, 2010 at 06:20 UTC ( #875950=monkdiscuss: print w/replies, xml ) Need Help??

I am trying to prepare a little overview of the activity of various parts of the Perl Community. I wonder if there are ready made statistics about the Perl Monks or if someone could fetch and make public some of the following?

Data would be interesting for both the whole life of PerlMonks and for the last 12 months:

  • Number of registered users
  • Number of registered users who posted
  • Number of people who posted on opening node
  • Number of people who replied
  • Number of new opening nodes
  • Number of new nodes
  • Number of Anonymous nodes
  • Number of visitors
  • Number of page views
  • Number of messages messages in the Chatterbox
  • Number of people who commented in the Chatterbox

Replies are listed 'Best First'.

    For cheap thrills, I entered into The Wayback Machine. Unfortunately, only five dates came up, as shown below. I added today's "Best Nodes" for comparison:

    • Mar 05 2007 Best nodes: month 83-135 votes, year: 121-194 votes
    • Oct 10 2007 Best nodes: month 73-105 votes, year: 113-230 votes
    • Dec 08 2007 Best nodes: month 71-132 votes, year: 115-238 votes
    • Feb 14 2008 Best nodes: month 84-126 votes, year: 111-245 votes
    • Apr 24 2008 Best nodes: month 77-111 votes, year: 111-156 votes
    • Dec 08 2010 Best nodes: month 42-94 votes, year: 72-144 votes
    Perhaps the most reliable indicator here is the lowest "best node" because the highest one often tends to be an "outlier" (that is, a freakishly popular node) while the lowest ones in the top 10 and top 20 lists tend to have similar values.

    Based on these numbers (and my own random observations) the voting at Perl Monks seems to have declined considerably, especially in the past year or so. Maybe we lost quite a few users after getting hacked in July 2009?

      I guess Stack Overflow also took a considerable amount of traffic, especially of newbies.

    Filtering all system-like messages from my IRC log from #cbstream - which wasn't connected 100% - I get 451258 lines since 2008-06-25 18:13:19.

    That is 111692 in 2008, 183631 in 2009, and 155935 in 2010:

    2008-06 => 2044 2008-07 => 13566 2008-08 => 21279 2008-09 => 23197 2008-10 => 18291 2008-11 => 13474 2008-12 => 19792 2009-01 => 21103 2009-02 => 18631 2009-03 => 19685 2009-04 => 19071 2009-05 => 11834 2009-06 => 12290 2009-07 => 15144 2009-08 => 19563 2009-09 => 13468 2009-10 => 13521 2009-11 => 8969 2009-12 => 10352 2010-01 => 10397 2010-02 => 12994 2010-03 => 15667 2010-04 => 15115 2010-05 => 11892 2010-06 => 7966 2010-07 => 14646 2010-08 => 13726 2010-09 => 21651 2010-10 => 17322 2010-11 => 11864 2010-12 => 2695

    Enjoy, Have FUN! H.Merijn

    Number of people who gave answers
    While all of your other questions can be answered if someone has access to the database (assuming no data was lost overtime), I wonder how one would measure this. A lot of replies aren't answers. Some of those replies don't even attempt to answer. Sometimes, there are replies to nodes that do not contain a question.

    This reply for instance, is not an answer.

      My intention was the "replies" just the wording was not correct. Fixing it now.

      This reply for instance, is not an answer.

    # Number of registered users

    # Number of registered users who posted

    # Number of people who posted on opening node

    # Number of people who replied

    # Number of new opening nodes

    # Number of new nodes

    # Number of Anonymous nodes

    should be possible with google sitesearch, grepping date and "by Anonymous monk" and specifiers like in-url: or in-title:

    for instance as a start

    questions 2010 : 16,900 results

    Anonymous questions 2010 : 1,510 results

    Number of registered users
    Number of Monks by Level
    Number of new nodes
    What do you mean by "new"? If you just want to know the number of nodes, the node ids are assigned sequentially.
    Number of new opening nodes
    Again, I don't know what "new" means, so I guess you mean all nodes. You can't easily query this statistics, but I think there's no harm in telling you the counts of root nodes for some sections. (A few sections are omitted on purpose.) The following numbers are current as of this post, will not be updated later, and include unapproved and even reaped nodes.

    Number of Anonymous nodes
    This one is easy, you can query the list of all of them on Anonymous Monk's writeups: the count listed is often inaccurate, but you can figure out the exact count by changing the "starting at" field.
    Number of page viewers
    There used to be some statistics of this at Most Visited Nodes and Yesterday's most-visited nodes, but they don't work anymore, the numbers are stale.
    Number of messages in the Chatterbox, number of people who commented in the chatterbox
    As mentioned by others, you can get the numbers for a one-week window from mojotoad's cbstats or from Tanktalus' cbstats. If you just want to know the numbers from the start of time, the number of messages might be related to the message ids you can see in the Tickers, but I've no idea if these started from 1, I think they might have been reset once, and I think they include private messages and possibly other things too. As for the number of monks who ever talked in the chatterbox, the gods may be able to extract an approximation for this number by looking at how many users have a last_chatter setting. This setting stores the last line you talked in the chatterbox, so that the site can filter accidental double submits.
      Thanks for the data. By "new" I meant new in the last 12 month. In the long run it would be nice to see an ongoing report about the number of nodes create per month. Also the monthly change in the other numbers would be interesting.

        If you just need to know the number of nodes in any particular month, you can use Super Search to find the node id of the last node until any date. Most node ids are allocated to actual writeups, whether replies or root nodes: reaped spam nodes are included, and a few new pmdev-only nodes (posts or pmdevnotes). There's no such easy way to find out the number of root nodes (or the number of sopws, that is almost the same number) in a time interval.
