TwitMee & lib
2013 fix/update: http://code.google.com/p/delphi-twitter-library/
Edit June 2012: This twitter library is now deprecated and will no longer be updated. I’ve rewritten it as a generic OAuth lib to use with both Twitter and Imgur (and any other OAuth 1.0 services) for a closed source project.
Extremelly simplistic and lightweight Twitter Client. No fancy graphics and complicated settings, only send status updates. Just type and click.
– Install: no install required, just run the exe from anywhere, it will store access details and be ready to send right away next time you start it. Doesn’t need any frameworks like .net, air etc , pure win32 app.
– Supports UNICODE, you can send status updates in Japanese etc.
