It strikes me that the 'nobody has used this tag' line, which appears on tags people have added and then all removed (e.g. kath 'n' kim), is always technically false, since those tags were in use at some point; genuinely never-used tags produce 500 Application Errors. It would be more accurate to say 'nobody is using this tag'.
Be quiet you ... and let me continue my evil doing in peace because I am an immoral person and now I will go on and fill the tags of all my badass words with evil spam... muhahahahh...! oh, no, don't be alarmed all my eviltagdoing has been undone. Actually im a quiet person, who like ... you guessed it : wordies! Thank you reesatee for letting me know how loquacious I have been in a heartwarm but direct way. And to any frightned pigs... next time my name pops up in a correspondance, let it be near my profile page.... right? And I second the opinion about emphasizing how the site is used and should be maintained by us, (yes I'm one of you guys now.. ha!), and future wordies. Nobody would like to see wordie.org, turn in to a chickenrally of gossip and hearsay.
In general, people can use the site however they like, as long as it doesn't interfere with other people's use, but those long tags are somewhat disruptive. And they often break the tag page, since I'm not escaping shit properly.
At some point the comment system will become more fine-grained, but the limiting factor at the moment is me. Just don't have the time to do it right now.
But I will write a little tagging tutorial right now, similar to the stolen html guide, and link to it from the tag box. That might help sort things.
One or several people are using tags to get definitions that stay at the top of the page. I tried this early on in my first few days on Wordie, but then deleted them when I saw it didn't fit the way people were using the site. Should we resist it or embrace? Maybe we need to revisit the decision not to have definitions separable from comments.
