Adding to WikiPedia is addictive…
I am constantly using my blog as a notebook. I will get obsessed with something and gorge on all the data I can find on the subject. Then, later when I’m looking for something, I’ll remember I scoured the net for something and annotated all the information in a blog entry, so I just run a search on my own blog.
So in that regard Wikipedia is like a blog for stuff you don’t really need on your own site, with entries maintained by other people.
There are no limits to participating. Periodically there are “edit wars” on some topics (e.g. the phrasing in controversial entries like Israel-Palestinian tensions). However the topics I look up / edit are usually so obscure that they are touched only rarely.
Wikipedia is truly awesome.
But if your blog gets fuller — we can always rename your site, “brain-pedia”
I meant that to be funny.
