The upsides are that the
results will likely contain some of the Web's most popular content and be spam free--as the engine only crawls content that has been hand-picked. The downside is that the index isn't nearly as robust
as users have come to expect, and 50 Matches doesn't utilize enough (or any) of a site's own info to help categorize the results.
"And there are absolutely no ways for visitors to 50 Matches to contribute (for instance by ranking listings or commenting on results)," the team says. "Visitors to a social powered search engine will have a more than an averagely high interest in contributing and could add value to the site."
