Note:  Not all dating site reviews are created equal. The most popular dating sites are usually a safe bet. Its good to join several sites instead of just one. This will broaden your playing field and allow youto feel out the site on a trial basis. After all, something as complicated as love shouldn't be too easily conquered by a simple search on a dating site.
