Threads bumping mechanism

Dear Imzy stuff.

First, you're awesome. Keep up the good work!

Second, I was thinking (and not for the first time): Some of the threads that we have in our communities are pretty interesting and lively. But after a day or two they are dropped down on the page and nobody sees them, hence the conversation is short lived (unless it's a sticky, but you don't want to have too many of those either).

Is there any chance of creating a bumping mechanism - a way to bump back a living thread up on the community page, so popular threads will have some priority over regular threads? Or any other way to keep up a thread without it being a sticky?

Thanks! And good day!
