Steve Rubel had a post recently about Nutshell, a free web service that brings social networking sites (Facebook, Twitter, LinkedIn, et al) to your inbox.  So I thought I'd try it.

For a lot of us, our e-mail has become the command center for our digital lives.  Bill paying, Keeping up with news,stock alerts and, oh yeah, communicating with friends have all become part of sorting through our inbox.  What was frustrating though was that to keep up with the ever-expanding social network world you had to either go to a website or use an application (like Seesmic Desktop or Tweetdeck).  

But Nutshell aims to fix that.  You can customize which social networks it checks, what information you receive (followers, unfollows, wall posts, etc), and when what time(s) you have it all sent to you.  

I've been using it about 2 days and my only complaint so far is that my LinkedIn account took 2 trys to work.  But otherwise it delivers as promised and could be a huge timesaver. 

The best part? You can comment, retweet, like, etc right from the e-mail.

Here's a screenshot of what the e-mails look like:
