I registered the skype name "bit.coin" ages ago when there was little interest in bitcoins.

I think skype now has around 600,000,000 users worldwide.
(could be wrong but they have hosted 70,000,000 calls at the same time so their userbase is huge)

Skype search only lists a tiny fraction of the full search, my account is #3 in the search for bitcoins.

There are only 4 good bitcoin names , bitcoin , bitcoins , bit.coin , bit.coins ,

So is it worth anything 

Would look professional as contact info on your website.

Spare me the blah blah blah about skype accounts being free, make me an offer if your interested
