I like it, but I'd also like to see a feature which Facebook uses which, by default, hides messages from people you do not follow. This, to me, is important. Sure, I can mute people, but as the platform grows, I'll have to spend all my time muting and that's a waste. I'd like to see followed messages given much more priority over random spam. Also, maybe a way to filter out links, like Twitter did with their DMs early on. If you tried to send a link, it failed.

I think spam is going to be more and more of a problem as the platform grows, so I hope we learn and improve on the lessons the other big social media platforms have already learned.
