So far the best site that I've found to gather information on all this type of software in one place. Both free and commercial applications.

There seems to be quite a bunch of blogs watching new startups now that I've started looking for them. Here's one more which made a good first impression on me. They have about 5 new posts a day at the moment.

From their site:

"We profile fledgling startups trying to understand what makes business tick (and what does not). In addition to this, we cover interesting websites, productivity tools and scripts, emerging technologies and interesting market research briefs."

During the last few days they have had about 5 new posts per day in average.

From the web page:

"The blog aims to provide hottest and latest information gathered by our in-depth research and understanding of technology world. StartupSquad.com is focused on the exciting ventures happening in US."
