Bitcoin has community momentum and developers who understand the protocol and the issues.
SC dev (is there even more than 1?) put in BETA code from bitcoin and then uses that as if to say it's ahead of bitcoin?  Pathetic.
Trust in the open source development team and other volunteers who eyeball the code is a critical part of why bitcoin is vastly more sound than SC.

Solidcoin is 'solid' like the Democratic Republic of North Korea is 'democratic' - and if the slimy claims on the solidcoin site didn't clue you in to that, you should be embarrassed.
