How hard is it, really, to type in the tags? Most of these add seven extra characters; some, like blockquote, are much longer (but not as frequently used). If you really want to make it simpler for yourself, type in the <p> tags (and the closing tags), copy them, and then past them each time you need a new paragraph. A simply ctrl-v will do it in windows and Linux; I'm sure MAC has a similar way to paste.
This Website is already hugely complicated and extensive. There are many cool features that were added to make our navigating and viewing easier, to enable us to simply link to other resources, etc. At some point, we just need to bite the bullet and live with a few things like HTML tags.
I've got a blog that requires me to type in square brackets around the HTML letters (like [b] [/b] for bold). I can't even imagine why they came up with that "improvement", but they have. And it's just one more thing I have to remember, that unnecessarily complicates my use of that resource. I prefer to keep it simple - or at least, as simple as we can.
