If you are into software business (development & marketing) then this forum is a must-visit each day:
You will find discussions on various topics such as SEO (Search Engine Optimization), registration services, marketing strategies, tips, software development trends, markets, software tools etc etc.
Most of the participants are mISV (Micro ISV). However, the discussions there are helpful to both big and small ISVs.
I strongly recommend that you subscribe to there feed today.
I have been reading the forum topics for about 2 years. Their site is simple, neat and fast.
