I have started a list of social bookmarking websites @ http://socialbookmarksites.in which is daily updated. Friends please share your valuable thoughts.
You have got very good concept for your website, i really appreciate it. I like the content of the site and color of the site is looking pretty good
We suggest implementing HTML headings. You can include keywords in your headings. The initial heading (<H1>) should include your best keywords. Using only one <H1> heading per page will strengthen your SEO.
