First: You should have a Back to Top option. I am glad Twitter has infinite scroll, but what if I do not want to scroll infinitely back to the top? Yes, it has the Home link, but having a back to top option would make my browsing experience better, easier. Second: Don't show old, abandoned profiles in your Who to Follow or your searches. For crying out loud, some profiles have the last tweet dated back to 4-5 years ago, yet they are still being shown everywhere. I only want to see profiles with recent tweets (no more than a couple weeks old). Third: Can you guys come up with a system that will find and ban fake profiles? They are useless and annoying. And they are everywhere. I know it's a tough one. You should come up with your own Twitter Panda that will help you spot and remove fake profiles. Or just having something like a text message to cell phone verification process on sign up would significantly reduce the amount of fake profiles being created. (Allowing only 2-3 profiles total per any cell phone #).
