BlastGroups.com - Easy Group Sharing

I guess you could think of Blastgroups.com as a sort of Twitter for grown ups.

Through the site, you’ll be able to share information from your computer or the web with your friends, for free. This will allow you to let your friends see family pictures, your coworkers see an interesting article, or basically anything else you can think of. All you have to do is create an account and find friends of yours who are using the service too. Afterwards, you’ll be able to manage your friends, labeling and grouping them together in a way that allows you to share different content with different groups. This is a good way to get in touch with people only when it is important, they don’t have to be reading every update you send out. If you don’t have many friends that are currently using the service, you can invite them or join pre-established groups. These have topics, so you’ll be able to come across interesting information or share some with the members.
