Thank you for this comment. I truly belive in the power of positive reenforcement over the alternative.
The “white” list over the “black” list.
You invest your effort in the right place because building a “white” list is buildding an asset vs. growing a “black” list is collecting trash (or adding more liability).
I like the approch that Twingly took and wish you a succesful path of growth.

you really get what we are trying to accomplish, I like that. Using Twitter’s data stream for gaining an edge in the compromise between immediacy and relevance is surely an idea we’ve been playing around with. Only using trusted blogger’s Twitts is an excellent improvement, thank you! The Google Reader share stream is something we’ll take into account as well.

Great post!

Cheers, Martin
