There are services out there for sites like twitter so you can share links, apparently a guy bought a domain and hopes to sell it for $525,000(at the time of this posting). Sucks for him because he's not going to get that much.
Buzz allows you to post links and also allows embedding images so buzzlink.com(a possible site similar to bit.ly) is totally pointless.
Oh well atleast domain names are cheap normally, he probably didn't pay much originally.
To see what's currently on buzzlink.com check it out here
