Review: I have had good luck with POF.
Those who have had hard times surfing the site probably should spend more time navigating through the pages.
If you click on in box and search you will notice different headings appear for you to click on.
Thus far I have been on POF for a year now. Have not found exactly what I have been looking for, but have been fortunate to meet some rather nice women.
As for selection, there are alot of single women out there with kids.
My preference is to date someone without kids, so the capability of searching with several different categories of search is very nice.
Its a free site. What more could one ask for. As for who you meet on the site, you must be careful with meeting anyone almost anywhere you are.
My feeling is the site is doing just fine. What bothers me the most is that if you get a email from someone it is simply polite to just let that person know in a kind way you are not interested or attracted to the profile. It shows respect and courtesy.
Hopefully my 2 cents has been somewhat helpuful to those who take the site seriously and use it for its true intention as a dating site. Good luck!
