Bitcoin is an implementation of Wei Dai's b-money proposal http://weidai.com/bmoney.txt on Cypherpunks http://en.wikipedia.org/wiki/Cypherpunks in 1998 and Nick Szabo's Bitgold proposal http://unenumerated.blogspot.com/2005/12/bit-gold.html
The timing is strange, just as we are getting a rapid increase in 3rd party coverage after getting slashdotted. I hope there's not a big hurry to wrap the discussion and decide. How long does Wikipedia typically leave a question like that open for comment?
It would help to condense the article and make it less promotional sounding as soon as possible. Just letting people know what it is, where it fits into the electronic money space, not trying to convince them that it's good. They probably want something that just generally identifies what it is, not tries to explain all about how it works.
If you post in http://en.wikipedia.org/wiki/Wikipedia:Articles_for_deletion/Bitcoin please don't say "yeah, but bitcoin is really important and special so the rules shouldn't apply" or argue that the rule is dumb or unfair. That only makes it worse. Try to address how the rule is satisfied.
Search "bitcoin" on google and see if you can find more big references in addition to the infoworld and slashdot ones. There may be very recent stuff being written by reporters who heard about it from the slashdot article.
I hope it doesn't get deleted. If it does, it'll be hard to overcome the presumption. Institutional momentum is to stick with the last decision. (edit: or at least I assume so, that's how the world usually works, but maybe Wiki is different)
