Much like front-runner political candidates, mainstream social media sites often get more attention than up-and-coming ones. There are, however, compelling reasons to look at newer beta and/or less well known sites. Some sites provide new services or features, or recombine old ones in unique ways. Others compliment or build on the functions of existing social media or other sites. The following four websites are ones that social media site users and bloggers alike should be aware of, and that already successful social sites should look to for new ideas.

(1) Romlet is a great way to build a reputation online as well as valuable PR and traffic via (free) backlinks. The Romlet widget combines and condenses some of the best aspects of a variety of useful and successful widgets. It also has the potential to develop into new kind of social network. The widget itself is part stats counter, part brag badge and part social bookmarking tool. Similar to the MyBlogLog recent visitors widget, the Romlet widget shows where visitors came from. These sources are displayed as favicon links to the referring source, which also work like AddThis bookmarks. Romlet users can also choose to display the number of visitors from each source, like a FeedBurner stats widget. Users can also visit their custom Romlet homepage to see more information and statistics about their own site or about other Romlet user sites and articles.

Romlet is still short on some potential community-building functions, a by-product of how new the site and widget are. Over time more functionality should certainly be added to encourage greater interaction between Romlet users. Social news and bookmarking options could potentially build on the already successful aspects of the widget. As with Peopleized, however, Romlet‘s creators continue to develop new functions based on user feedback.

(2) Peopleized is a relatively new social networking site where people interview one another in order to build up popularity and network with other people in an area of interest. Many of the site’s current users are bloggers, but not all. People can post or quote their interviews or others on their own website or social networking profile. These interviews serve multiple functions: building up PR on an established website, getting exposure to new audiences and developing press release information and skills for future use.

Probably the biggest limitation of Peopleized right now is that the functionality is not completely built out for hosting interviews and other information on remote sites. Most of the action takes place on the site itself, which is a good start (considering the site’s high levels of traffic) but could be expanded upon. Fortunately, the creators of Peopleized are already working on expanding its capabilities on major social networking sites such as Facebook.

(3) Plime is a social news site with a fairly complex and successful system for organizing and presenting content in various categories. First, there are more ‘offbeat’ categories than on most social news sites, including WTF and weird. Each story submitted can be easily tagged with an image, something Digg and Reddit would do well to take notice of. Plime voting also works in a fairly innovative way: votes are automatically given to new stories based on how many users have upmodded the user who submitted that story. Like StumbleUpon, users can also indicate categories of interest. In short, Plime integrates some of the best features from major social news sites.

The biggest downside right now is that, due to a lack of users, the site seems to recycle a lot of the material presented on said major social sites. The biggest upside for content creators is that the site doesn’t seem to put a lot of weight on where a story is submitted from – favoring content over existing URL popularity, making it a great place to submit stuff (yours or that of someone else) from lesser-known websites.

(4) Shoutwire is another social news site that has been around for some time but is relatively under-appreciated, particularly by people who want to get their content out into the world. The site works a lot like mainstream social media sites, but is perhaps less well organized. To compensate, however, it offers more options for user-submitted content – including forums for discussion and on-site editorials. Also, ShoutWire sends a significant amount of traffic to sites that successfully get voted to the front page. Admittedly, the traffic volume doesn’t compare to sites like Digg, but anywhere from a few thousand to over ten thousand hits from 20 votes is nothing to scoff at.

ShoutWire

Usability and ease of navigation seem to be the major drawbacks of ShoutWire. It is somewhat hard to find anything but the front page and almost-popular or newly-submitted upcoming articles. Something like Digg’s cloud view or more obvious category searches would greatly improve the existing site. That being said, for someone either casually looking for front-page news or hoping to get some traffic to a less-established site: ShoutWire is easy and user-friendly.

These are, of course, just a few examples. What underrepresented or under-appreciated social news, networking or bookmarking sites do you enjoy? Do you use some of these already? What is your take on them?
