Read about this on mashable, started to check it out but I wanted to post it up here. If you like Digg but do not like hunting for what you want and you like the StumbleUpon model, then DiggStr might be for you.
From what I have seen they are not owned or affiliated with Digg or StumbleUpon but they seem to have some sort of agreement with Digg.
I guess, check it out and let us know what you think as I will. For the record, the guy on Mashable thinks its great but said he is not ready to abandon Digg for this newbie.
