Online Dating

I am a single 32 year old woman. I live in a city where it's hard to date. So, I turn to the internet to help me find a date. At this time in my life, I've pretty much tried all the major dating sites (Match, Yahoo, Eharmony, Chemistry and even Plenty of Fish). I believe in being honest when it comes to my online profiles, but it drives me crazy when people who have qualities that I'm not looking for contact me. And it's pretty much every guy who contacts me... Maybe I'm too picky, or have my standards set too high, but I know that there are a few things that I am not going to budge on. For example:
*You must be taller than me. I know I'm short and most people are taller than me, but I would like to think that by dating a guy who is 5'6" or taller I am giving my future children a chance at not being a midget. So I have on my profile that I would like to date a guy taller than 5'6". I'm sure that there are some guys that are shorter than that who are great guys, but I'm stubborn, ok.
*You MUST NOT SMOKE. I might make an exception if you only smoke when you drink, unless you drink on a daily basis. I think smoking is a gross habbit and I don't want to kiss an ash tray. I know I have dated a smoker in the past and have gone out on a few dates with one recently. However the more I think about it, the harder it is for me to breathe. No smokers, please.
*You must have some sort of a college education. I'm ok with a bachelors degree, advanced degrees are welcome. I don't care if you just graduated at 34, but I worked hard to get my education and think you should as well. Again, I'm sure that there are guys out there who didn't go to college who are great guys... call me a snob if you want.
*You must spell check what you write me. Do I even have to explain this one further?
*You must not be separated. I will make an exception if you are fully divorced (preferrably if the divorce happened 3+ years ago). I've dated a newly divorced person and there is a lot of baggage still. I can only imagine if the papers haven't even been signed yet...

And some I might teeter on a little:
*Kids. I keep going back and forth on this one. I'm not even sure that I want them myself. I think that as long as there isn't a lot of drama surrounding it, I might be able to date someone with kids. Still not sure on this one though. Guess it depends on the guy.
*Location. If you live in the DC area, you will understand this one. Even though according to google maps, Gaithersburg is only 30 miles away, that could mean up to 3 hours to get there from my house. Call me lazy, but I would prefer you lived inside the Beltway, please.

Bottom line, I'm pretty honest about these things in my profile. If you are going to contact me, please read my profile. And if I don't contact you because you have one of the traits above, don't continue to email/wink/chat me if I don't respond. That will get you blocked.

Is it just me? Should I start lying in my profiles? Should I be less picky? What am I doing wrong?
