You might find it handy to delete your DM chain on twitter from time to time. I found it quite hard to do on a mobile device, but via the desktop it was pretty straightforward.

As you can see, this sets us up for a much cleaner interface, which helps facilitate discussion of future favors and upgrades.

Cheers.
I find the iPhone app to be easiest. When viewing all DM’s just swipe left and hit the trash can on the ones you don’t want.
I tried but could find the Hyatt chain… :/
Strange
Thanks for the Twitter information on DM. I always wondered how to do that, have never had the need yet, but it might come in very handy one day. F
