I've tried alot of online dating before (have posted on the subject here before as well) , but after all of my experience with it, I can say that ultimately , IMO at least, about 95% of the time, maybe MORE , it doesn't work for sh*t quite frankly.
You may go on a few random dates, or first-time "real time meet ups" here or there, if you've got at least some looks going in your favour (& don't let anybody tell you that it's really all about the profile; w/online dating women are shopping the same way men always shop - they either like your looks right off the bat or they just keep browsing). You may even get laid a time or two, or three, if you meet the right girl at the right time.
If your goals are to go on a few random dates, that more than likely will never get off the ground or progress up to or past "date #2", and possibly ( and I do stress possibly) get lucky once in a blue moon, then by all means pay 29 bucks a month or whatever it is to keep a profile active. You'll probably get what you're looking for eventually, IF that's all you're really looking for. BUT, if you're looking for real love, or for a real g/f, again IMO at least, online dating just doesn't work for sh*t. Why? Well, honestly, I just feel that two people "connecting" via computer profiles is just ........ well......... NOT how it's really done. There's something to be said for the "old fashioned way"; the tried and true methods. It hasn't ever been done via computer "matching" in the past, in the whole vast history of humankind BEFORE the advent of online dating. And the majority of successful relationships you see around you are (most probably at least) NOT people who met "online". So , to sum up, and you can take my advice if you want or discard it if you want ( I do , unfortunately, have years of "field research" under my belt w/just about every kind of online dating scene) , my advice is if you're just looking to goof around and kill some time, MAYbe get a date or two here or there, then do the online dating thing. When you're done f'ing around and you're ready to play in the majors full-time, dump the lame-ass online scene entirely and redirect any energies you were previously putting into crafting profiles towards full time real time action.
