A lurker of this site for some time...I find it inspirational and a good place to look for information involving design topics.
Also, the fascination of this site revolves around how well people play together here. I know there are occasional editing fights and such, but for the most part the people on this WikiServer are very respectful. Quite a bit different from the Internet as a whole.
I have started writing yet another wiki clone. I have written the grammar using javacc and I want to mimic the wiki syntax of this site. However things like mismatching quote like
heh'
is a lot tougher than I originally thought. Without some of these problems the grammar matches things okay.
