Match.com
Match.com
This is among the more recognizable list of web dating services. This site is user friendly and has a lot of members so you're more likely to find what you're looking for. They have a "Make Love Happen Guarantee " feature that says if you don't find anyone in 6 months they'll give you 6 months for free, which sounds like a good deal. Some complaints were about automatic membership renewal - they continue charging your account even if you've canceled. Sites that have this usually have problems. Other problems were with the Daily 5 feature where match.com will send you 5 people a day, some members complain that those matches weren't matches at all. Beyond that, the volume of people makes it more likely to find someone to hang out with. So it wouldn't hurt to try it out.
There are tons of web dating services on the net and plenty of reviews, so if you're not finding people in real life, online dating sites might be something to look into. Some good review sites are viewpoints.com, About.com:Dating and DatingSitesReviews.com . Good luck.
