Some suggestions.
One: Learn correct English. Nowhere in the English language is there instruction to use multiple exclamation marks. Your idea isn't brought across more powerfully, it is looked at as immature and spam.
Second: All capitals is seen as shouting. Also falls under the immature category. Why are you yelling at me?
Take a look at the forums. There are hundreds if not thousands of threads teaching about seo. SEO in part requires backlinks and the majority of this forum is in relation to that in some form. A social networking site must be attractive and have a reason to displace a forum, facebook and any other form of socializing that your target users would be currently using.
On top of it all, your site looks like a 12 year old made his first website. If you want to be taken seriously, you need to put money into getting a quality designed site or learn how to design something legit. If you're not willing to do this, give up now. You'll save yourself time and frustration because as your site is designed now, it's not going to get much traffic and the traffic you manage to get will have a higher bounce than Blake Griffin.
