Reddit already has everything in place that you need to replace Twitter. Actually, it is better than Twitter in all of these ways:

• Self-moderation
• Variety of post types
• Better structure for discussions
• Premium membership for $6/mo
• Smarter crowd?

You can follow people on Reddit, so all they need to make it work as a Twitter-replacement as well is:

• Short form posts than can be filtered for
• User home pages that are their own communities (already exists, post to your profile)

In fact, anyone can make their own community. Famous people can “blue tick” themselves by simply linking to it from somewhere else they are verified. And short posts are already do-able.

Reddit can make this happen. The amount of coding is minimal, and they would get enough new users to get the valuations and users for an IPO that they are planning anyway.

You can post on Reddit and have it automatically share in on Twitter. It doesn’t look amazing, but you can use the Reddit title to be your “tweet”.
