Oh, and can't people figure out how to rotage images 90 degrees? Is that so hard--google it if you need to.

Hate photos of men without shirts, or ones showing them wearing sunglasses, hats--the first one is just "ewww", the latter two tend to hide the person's looks--which I supposed might be the reason for posting them in the first place! And fish pictures---don't get me started.

I also get the impression that at times men want to find a female version of themselves--someone who enjoys watching football, fishing, working out. I tend to shy away from these types.

Another pet peeve of mine: When a gentleman says that they would love to see their prospective mate having the ability to look "great in heels and a little black dress", but "just as comfortable in a pair of jeans and a t-shirt". First of all, I think these guys are paying too much attention to how the woman looks versus other more interesting characteristics such as compassion, hobbies, intellect. Also, can you get any less original? You guys can do better than that!

Do include pictures, and keep your clothes on in them unless you're only looking to get laid. Be honest. I know that should be a given, but it certainly hasn't been my experience. Don't inflate your education then write a profile full of spelling and grammatical errors. In my experience, when a man says he's 'self employed' he's really unemployed. Do bother to write out a profile. If you can be funny that's a plus.
I know you didn't ask about approaches, but I would say for most women starting out with something like, "Hello, beautiful" is going to get a hard pass. What will get you some attention is an indication that you've read the woman's profile.

What is up with the bathroom pics ? Is that the only place that you're able to take a picture ?
Why do you look angry on your profile picture ?
What's wrong with smiling ?

One thing in particular which bugs the crap out of me...don't have only one photo of two or more people! If I have to guess who you are, I'm not biting the bait. Also, men, we don't want to see a photo of you and your ex!

Something I've found hilariously entertaining is to listen to the "expert" dating advice offered to the opposite sex. I'm a man so the ones giving advice to women on how to get men for example. Many are so ridiculous that I would seriously question the sanity of any woman acting like they recommend. When you do find someone that does seem reasonable, use that advice just switch genders. A casual friendly approach that you would like would probably get you a better reception than "projecting alpha male confidence"

Picture please! Things you're interested in and positions you hold about important stuff are nice. Personally when I see negative language about past partners or women in general, I give those profiles a hard pass. I assume those men either just don't like women very much or are so bitter and jaded that no matter what I'M like, I'll be paying for whatever wrongs they feel women have done them in the past.

I date men and women, so this applies to both.
Photos: please include some, at least one recent photo. If we meet, we’re going to see each other anyway!
Profile: actually write one, even a short bio. Include important info like belief, political stance, social habits like tobacco/alcohol, marital status(disturbing number of married men on sites), pet preference(chatted with one who was jealous of my dog and wanted me to ‘get rid’ of her! Nope!!!), and at least a few interests/hobbies.

These are things I look for, first. No photo, I don’t respond. I check through the preferences...don’t respond to right-wingers, ever. I’d rather have basic facts like these BEFORE I decide to respond.

I hear duck pics are good

I've often wondered,the young Women of High School,how has their life gone,did they marry the Man of their dreams,have children to make them proud,and be a success in what ever they tried to do? Or now wishing the choices they made were different? Maybe the "Loner" or Nerd they rejected as being beneath them,not worthy of their time,became a success on an invention or process? I dunno,no one's invented a time machine ,to go back and change how things went.

I'll start. Ladies, try and avoid too much negative language on your profile. A list of things you want in a relationship is way more interesting than a list of things you don't want.
