"It filters out the posts that are least interesting to you and leaves only the stuff that is relevant."<p>How well does this service work in practice? I imagine telling spam and non-spam emails apart is far easier then "predicting" which blog post I will like.
just some unrelated feedback about how i have been dealing with this feed information overload issue for now: i use feedly which utilizes among other things google reader friends.. so pretty much i rely on hundreds of other people to decide for me what is interesting and i check the stories they upvote/recommend/share
I think it's an interesting idea. I track about 200 feeds, but probably look at only a small percentage of the stories. I definitely would appreciate help in blocking out the least interesting stories.<p>That said, limiting the free account to only 3 feeds makes it difficult to judge the site's usefulness. I guess that I would probably want to try the site out with at least 50 feeds to see if I wanted to pay for the ability to track even more feeds.<p>Consider that it may be more valuable to give out fewer invitations but raise with numbers of free feeds per user.
