One of the biggest online dating sites is the Plenty of Fish dating site. Not only is Plentyoffish.com one of the largest dating sites in the world but it is also completely FREE!

Of course there are some issues with a free dating site. One being that the quality might not considered to be as good as a paid dating site such as Match.com or eHarmony. However, in my personal experience, Plenty of Fish does offer a pretty decent dating service and any lack of quality, it makes up for in quantity. Yes, there might be some bad apples in the dating pool but these people can be easily ignored through the sites filtering tools or by simply ignoring them outright. This allows you to put your energy and focus towards those that are worthy and dateable.
