37signals, the creators of Basecamp, have launched a new free online app called Ta-da Lists. The application is an excellent example of ’simple but powerful’ and would be a great tool for any microISV.
The original announcement for Ta-da was posted on their blog and immediately got a huge response. The comments are well worth a read and are a great example of raving fans.
Update: Jason Fried of 37signals posts that 2500 people signed up in the first 24 hours Ta-da Lists was available. The original post was the only announcement made.
