I’ve added another update to ThinkTwit as of yesterday; this includes use of ordered lists (ol) instead of unordered lists (ul) as it is more semantically correct, removed some old code left over from some time back that was no longer necessary, and added the ability to output usernames instead of Twitter names.
The roadmap has been updated – check it out if you want to know what features will be coming soon, and feel free to provide suggestions.
