I'm looking for features in websites that I may not have seen before that are unique, and are excellent features that not only improve the user-experience, but help the surfers come back for more. Such as:StackOverflow's status update banner (seriously now this is awesome.)RSS feeds (when they were new)Hotlinks to social networks (facebook, twitter, etc..)Auto-posting to social networks (popup and auto-post link/content)Mobile phone integrationOpenID login passthroughAJAX push/pull technology for content updatestinyUrl and others that concatenate URLS shorter.I can think of many more, but if there is something you've seen that is unique to a site or isn't very well known, I'd love to know.
What features in a website make you want to revisit?

None of those features would encourage me to revisit a website. They're nice and all but they don't offer me any incentive to want to come back. (RSS may get me to come back but only because I see new content I may be interested in, not because the site uses RSS).Stuff that does make me want to come back:Rewards - The point system as the stackexchange sites are an example of a reward. I get points for doing something that helps the community grow (i.e. provide good questions and answers).Fresh & interesting content - I won't come back for any wow factor as that wears off quickly (usually after the first visit). I will come back for new content that I find interesting, useful, and/or amusing.Benefits - I don't mean the website offers me health insurance! By participating in a website I somehow benefit from it. Example: I write articles for a website, I know get to say I am a published author. I participate in a forum and achieve a high status, I get to say I am an expert in whatever topic I cover and/or I can drum up some business for myself.
