I don’t want to make a habit of this, but I need to single out a company, again. Rollyo: you roll your own search. Basically, you start a new search ‘roll’ for which you provide a list of websites/sources you want searched. Then, you can use keyword search to find what you want within that search roll. Basically, the service allows you to define your own searched universe, if you will. Of course, Rollyo allows you to search the ‘whole’ web, if you were curious how comprehensive your roll relative to the entire web. Last but not least, since it”s a “web 2.0″ company (I am being facetious here), of course you can tag and share your search roll.

Now, at the first glance, that seems great: more power in the hands of the user, right? Well, if we ever have time to get to even using it since there are, hmm, 20 other ‘web 2.0′ products that are taking the user”s time with tagging, sharing, categorizing, ranking … you get the picture.

Besides, one of the problems that traditional search engines help solve is finding sources that are unbeknown to the user. In this case, one can tie himself in his own search roll not knowing what else is out there … reminds me of the premise of republic.com.

Companies like Rollyo are moving in the opposite direction, making things that finally got easier, harder again!

Oh, I forgot to mention that Rollyo’s search (some would argue this is the hard part) is powered by Yahoo! Search. Hmm, have you ever tried Yahoo!’s Advanced Web Search option? Guess what? It may not be as pretty, but you have been able to ‘roll’ your own search there for as long as I can remember by specifying the sites to which you want to limit your search, separated by commas.

Hmm, I think there’s room for a search site that not only allows you to specify the sources, but also allows you to limit your search by the language of the websites! Wait a minute, that also is already covered by Yahoo!
