For those of you (and I know you are not insignificant in number here) who think of Bitcoin as a weapon to be used in the war against the establishment I can see that Bitcoin-Central's move may be seen as fraternising with the enemy.  I which case I can see that this is not a service for you.

However, for the rest of us it's a means of potentially integrating Bitcoin more into the normal lives of normal people and in terms of more widespread adoption I can't see (if it really does survive the potential attacks that are being pointed out) that being a bad thing.  To the contrary it will be doing a lot to broaden the userbase and consequently strengthen the project - and we all benefit from that regardless of whether we choose to use the service ourselves.
