Twitter is a product that is used and loved by hundreds of millions of users. The core product has needed the same basic features for the last 7 or 8 years. Here are the things I think Twitter should build. In this post, I stay away from areas I no longer understand for Twitter (e.g. zero rated Twitter / developing world products) or big picture ideas (e.g. how to remake the timeline). Even simple changes could go a long way for the product.
