I just checked this out, looks interesting.
"Do we really need more social networks? Looking at New York based Chris and Becky Carella's latest venture, Subjot, the answer could well be 'yes'.
Here's what caught my attention:
Subjot is not just another Twitter clone. There’s no denying that there’s a ton of similarities but there is one feature in particular which is pretty interesting – and that is the ability to curate the content you follow from other users. So instead of following all of their status updates, you can view a list of the topics they ‘jot’ about, and select only the ones that are of interest to you.
How does it work?
When sending an update, which is limited to 250 characters, you can accompany that update with a ‘subject’ of your choice. People who follow you can then select from your subjects what exactly they want to hear about.
