organising them by date, ie Today/Yesterday/Later is high on my list. I figured it would be important for people coming back to the site after an initial visit. But for that I'd need people making an initial visit first hence I thought I'd wait until I'd got some positive feedback before doing that.
Nothing on there should be more than 6 days old which was a guess by me as to how much history made sense to show. Possibly that needs to be more recent even, or maybe ordering by date will just make it less of a surprise when you find one which is gone already.
Thanks, I'll check that out. I've only been running it for a couple of weeks and have been actively developing it during that time so have possibly broken something and missed deleting some tweets at some point.
I do feel that you have built something quite useful.
