SocialMention is a new social media search engine that searches user-generated content such as blogs, comments, bookmarks, events, news, videos, and micro-blogging services. The service uses numerous sources to fetch respective content.

In search engine category it would be the first attempt at being search portal of social media related content along with user generated content especially Bookmarks, Comments & Microblogs at one place. Also, if we set the success factor apart (though my best wishes to SocialMention) it would be pretty good concept for online startups to further move this concept ahead.

All the while, SocialMention allows to easily track what people are saying about you, your company, a new product, or any topic across the web’s social media landscape in real-time.

Search results are aggregated from numerous popular social media sources, including Google blog search, Twitter, Delicious, FriendFeed, Flickr, Digg, YouTube etc. (SocialMention Sources) and remixed as a single stream of information. The data is fresh, which means you can track conversations as they are happening in real-time.

In addition to web-based search results, Social Mention also features email alerts and personalized RSS feeds for automatic and instant updates.

As few word of advice, I would suggest the portal should inculcate more blogs, services and content sources it carrying at moment which is almost handful. The concept is good though few tweaks could really make this service interesting and worthwhile indeed.
