New updates on the Quibbles app

We just rolled out a few updates and I thought to talk about them to give clarity.

1. You can now post directly to your profile and you don't have to always select a community. Note that the Home Screen now shows more of community posts and profile posts from people you're connected with. I think that makes sense to avoid noise and prioritize topic-based discussions.
2. There's now an explore screen which shows profile posts from everyone (even those you're not connected to) as well as video posts.
3. You can now update your username from your profile settings (same place you switch between light and dark modes), and you can make this change only once in 30 days.

Please desist from posting everything in broad communities such as Nigeria, interaction etc. Please use them cautiously to give readers a good experience. If in doubt, post to your profile or use the General community.
