Arten Science (http://www.artenscience.com/) has announced TwitQwik for Mac OS X. It offers a way to update your Twitter status and upload photographs from your Mac.
TwitQwik doesn’t download your tweets, leaving you to read those at your leisure using your existing favorite Twitter client. The app purportedly has no advertisements, no spyware and uses minimal system resources.
TwitQwik is free unless you’re using it within a company or enterprise in which case a site license is available for US$100. This also provides you with a customized version with your own logo.
