    hey guys,
    im new arround here and i was wondering..
    i saw in the last 2 years alot of social bookmarking and news websites that give ppl to post links news, and i was wondering, are the links from such a website are really strong and affect anything??
    and whats the reason of social news and bookmarketing website anyway?
    should i open few new websites like those myself??
