Real-time search is one of the newest battlegrounds on the web. In fact, history may show real-time search as the development that saved social media sites like Twitter and Facebook as stand-alone entities.

You see, despite all of the growing attraction of web users to social media sites, the ugly truth is that most social media sites have never been able to show a long-term profit. Myspace has been the exception since completing a 3 year, $900 million advertising contract with Google in 2006, but there is no way to know whether Myspace will be able to maintain their Google contract or their profitability.
One common way of start-up companies making money is to auction their business to the best offer such as when Google bought Youtube. There have been rumors of numerous companies from Microsoft to Google and even Apple buying up Twitter.
Real-time search may just re-define how users use the internet. It is the ultimate combination of search and social media. Searching real-time information allows engines that provide the service to display as results that are happening across the web without delay. Since social media postings are updated frequently they are easily able to gain dominance in this sort of platform over traditional articles or blogs. Combining these results with ads seems to be the obvious sought after answer to the profitability questions. Below are some of the hottest real-time search engines across the web.
General Real Time Search

Collecta: This site has not quite reached beta, but the home page does provide two example sneak-peaks. The layout is likely to change before it gets to beta.

Google: Google recently launched a number of new features, and real-time search is one of them. This is found by doing a search from the Google main page, and then selecting “show options” directly under the Google logo. One of the options available is “Past 24 Hours”. Larry Page recently discussed real-time search at the Google Zeitgeist conference in the UK. It is difficult to imagine Google being left behind in anything search-related. The results from this page appear to contain very few, if any social media pages, so it is possible that Google is focused on displaying links that come from already trusted sources.

OneRiot: From the searches I’ve done this site also appears to show links indexed from posts on social media sites purely. They appear to rank the posts by popularity (re-tweets, diggs, ect. ) and how recently they were posted. Each link shows the original author’s logo or profile picture that posted the indexed link so that credit is given. While each of the sites give credit to the original posting author, this extra step may be the distinguishing feature makes OneRiot more favorable. The layout is a basic vertical format.

Scoopler: My favorite between each of these has been a toss-up between Scoopler and OneRiot. Scoopler appears to index any links it from posts all over the web as fast as possible, though I did not notice any repeat links. While this allows for seeing a lot of information this also allows for a site like Twitter to dominate the results. To combat one domain dominating the results the site provides popular searches and popular links that are posted throughout the web. The site also automatically displays the next result on the page without requiring the user to refresh or click a button. The layout is probably the best out of the four general real-time search engines.
Twitter-Based Real Time Search

Twitter Search: The search feature allows a user to search all of Twitter’s posts for the specific keywords. While the search is only for Twitter users it is a very powerful tool.

TweetMeme: This tries to display Twitter posts by popularity as well as organizing the posts by categories. It has a search option that mimics Twitter Search for the most part, and each link has a button that allows the user to re-Tweet the link in question. There also seems to be a lot of integrating features with Twitter, which may help it keep from being disregarded as Twitter Search expands.

Twitmatic: Much like TweetMeme, Twitmatic tries to integrate with Twitter by having a Twitter login link directly on the page. It only indexes videos posted on Twitter. I tried multiple attempts to search on two different days with no success after at least 10 minutes. This service will need to be at least serviceable to attract users.
