Ask HN: Review Refynr.com: de-clutter Twitter

I'm at the Beta stage where I'm testing charging a one-time for Refynr, but want to find out if a) anyone is really interesting in filtering Twitter & Facebook, and b) if they're interested, why aren't they willing to pay a one-time $5 fee?

What's Refynr.com?

It's a Twitter + FB client that filters out the clutter from your feeds, and then saves them for you to read later.

You may ask... Why not just unfollow? Or create Lists?

No individual posts interesting stuff 100% of the time, but that doesn't mean I don't want to follow them. I don't want to miss the cool things they tweet, etc. Lists are too hard to maintain, and can only contain up to 500 users. I want to simly refine my feeds with a lot of filter options (and foursquare & FF stuff should be filtered out by default!)

Why don't I put ads on Refynr.com instead of charging $5?

1) I'm solo and bootstrapping, so need more revenue than that 2) Don't you think ads would be kind of inconsistent with the concept of Refynr: keeping the clutter out?

Finally, is there something wrong with the site design or text that would keep you from paying a mere $5 for lifetime access to Refynr.com?

Do I not sell the idea well?

Is something off-putting?

Does it need a 30-day Trial?

TIA!
