SubmitStartup.com is a place for entrepreneurs to get useful information on blogs that you can approach to get your sites reviewed.
It definitely is a good idea because it captures all of the necessary marketing tools at one place. There are many other blogs like mine that will review startups on a regular basis. Finding the right one to get your sites reviewed is the key to success. Not all sites provides useful feedback to you so you can improve your site and make it even better.
SubmitStartup.com uses algorithm to rank every available blogs by traffic rank, page rank and simply the quality of the blog. This way you can find the right site and submit your information.
I recommend that you submit to as many sites as you want. It will not hurt to get reviews on all of the sites. Some only simply review your site; others review and provide comments; some others like mine, provide many other useful content.
