Wiki Tikki Tavi

I thought I would be cute and name this post Wiki Tikki Tavi for the alliteration value, obviously, but lo and behold there is actually a wiki search engine named thus so I am a day late and a dollar short and full of cliches to boot. Anyway, a look around the wiki world is tiring to say the least. I find wikis helpful and a good starting point for some research but the thing I find the most distressful is that no one seems to clean out the old stuff. Being a tidy person and the furthest thing from a pack rat, I can't stand to have old stuff keep popping up when I am looking for something current. I really don't need the particulars of signing up for a 5K race that happened in 2004! It's sorta like yard sale signs...when the sale is over, the signs should come down and when the info is no longer pertinent, please, somebody hit the delete button.
