@simonwoods I 100% agree on the exceprt field. I think one of the biggest problems on MB for encourageing engagement is that anything longer than 280 characters just becomes as single title with a link, which doesn't tell the reader much and requires extra action to see what something is about.

I think an excerpt field would be great, and for posts imported from places that don't support that (and maybe as a default if you dont' want to fill it out) just the first 280 characters of a post would be a good place to start.

Also agree on threading, maybe less so on the limits though.
