Should I use Plenty of Fish? Should I use OKCupid? These are both free online dating sites with millions of people on them. The huge database of online daters is a big plus for these sites. That’s the best way to play the numbers and be in front of the most potential matches. The downside of both Plenty of Fish and OkCupid, is that since it’s free, the bar to entry is lower and the people on the site may not be as serious about dating. When people are paying to join a dating site, like Match.com and eHarmony.com, they are likely to be more serious. There are also more safety barriers in place for people who use a paid online dating site. With Free Online Dating sites, there’s likely to be a higher percentage of scammers or people who don’t want to leave a paper trail on the free sites like OKCupid and Plenty of Fish. However there can certainly be shady characters on free sites, too. Also, we do have a success story from a doctor who met her match online on one of these free dating sites.
