Yesterday I sent an invitation to join StumbleUpon to all my Yahoo! contacts. It was not my intention, it was a mistake from me.

I want to apologize for having spammed you !

Nevertheless some of you (about 10) have joined StumbleUpon, I'm very grateful for the trust.

StumbleUpon is really a cool system and if you actually use it we can exchange what we find cool or interestig on the web.

So, once again sorry for the spam...
