Hi Thomas!

Thanks for your feedback. You don't sound harsh at all.

I think you're right. Space on mobile is precious. I made a deliberate choice of taking up more space to provide a greater sense of hierarchy and to make things really easy to read and scan. I believe that something like Twitter is never static and that people fluently scroll these interfaces. Twitter does prioritise information density at the moment, and, for me, it makes it harder to scan and read.

Regarding the extra plus sign on the profile, that's a fair point. I would be interested in testing it with users. I added it because it's a common pattern on other social networks to go on your profile and being able to add something new to it. But showing the same button twice might be a cause of confusion as well.

Once again, I'm not so concerned about how many trending topics I can see in one particular view. As a touch device, I think it's acceptable to invite users to interact with content.

Again, thanks for your comments. :)
