Shortly, each of the questions:
- Approve - certainly. This should we trust ourselves with.
- Frontpage - take it away, might as well. If it is worthy of frontpaging, someone *will* so that, and noone will get upset by you doing it yourself. It also saves a few new friars from doing that "mistake" (I've seen a few getting toasted for it).
- Consider - trickier. Mostly it seems to be used to save oneself from downvoting, which is bad, but if it is a dupe it is more ok. OTOH, a dupe will get considered by someone else, so I feel ok by removing this possibility too.
- Vote on your considered node - well, since some things seem to be based on number of votes for this or that (can someone clarify) it seems fair that you can't "save" your own node. OTOH, if it should go, it probably will get enough such votes anyway.
As long as a "good" rule can be established and enforced programatically, it is surely gonna easy the strain on the editors. But the problem lies probably in what is a "good rule". At least you have my opinions to the heap now. :)
You have moved into a dark place.
It is pitch black. You are likely to be eaten by a grue.
