As an organizer of the San Antonio SharePoint User Group, I get the opportunity to meet lots of new members of the SharePoint Community. For vendors new to me, one of the first things I do after visiting their website is check SharePointReviews.com for their listing. To me, that is a measure of SharePoint awareness at the company producing the product.
If you make a product for SharePoint, I recommend submitting your product to SharePointReviews.com. It won’t make your product more mature with it’s interaction with SharePoint, but it will give you a better look to the community.
When you visit the site, check out the Top Rated Products. You can find out what other people think of SharePoint Products and you might even find some ideas to improve your own work!
