Amazon has com up with an interesting approach to using twitter: they broadcast daily deals on music.
I think this is well done. They don’t abuse twitter or their followers because they are limiting it to one broadcast a day. And they are letting people in on good deals, making it more likely that people will want to follow them.
If you are interested in what they are doing, or want to find out more about the deals, see Twitter / amazonmp3
There is a story at the nytimes.com on how LinkedIn is getting an infusion of capital.
I think the reason is simple (and I’ve highlighted it in this quote:
“Now, in the midst of Silicon Valley’s recession-proof enthusiasm for community-oriented Web sites, the most boring of the social networks is finally grabbing the spotlight”
if community-oriented web sites are recession-proof to Silicon Valley, to me that is all the more reason that businesses should feel confident in proceeding quickly with their own plans for such sites.
