After much tweaking, I have a profile and pics that are working well. I'm getting very high message reply rates, around 50%, but things seem to fall apart after a few messages. The goals is to get a number or to meet as quickly as possible. As anyone found something that works well. What has been your experience with this site. I have found negging and cock/funny don't work very well unless done very carefully, but the typical guy message "hey what up your hot" is always ignored. What do you think? Any advice and feedback is welcome.

I have had a lot of success in Okc...

I usually start by making fun of something unimportant in their profile (i.e. "I guess I'll have to get pass the fact that you like Kesha" or "You do not like beets! This is a deal breaker"). Then I tell them why I'm writing them, like, really what I think it is interesting about them (preferably something they've written). Two brief paragraphs works for me, one about her, and one about something I'm up to these days. I also always ask one (and only one) question per message, at the very end. In the first or second message, I usually bring up some story about some girl I went in a date with or who hit on me and who was either crazy or had a ridiculous sense of entitlement, as in "I sure hope you are not like this girl the other night who..."

Rules I follow: I have a 3-4 messages rule. After I've written 3 or 4 messages, I either ask her out for coffee or, I feel her messages were too short, I ask for her number/facebook. I also follow the rule to wait to respond as much as she has taken to answer me; if she writes back right away, I always still wait 24 hours. I never write a message longer than her messages. If she does not write me back, I wait one week and then write a one sentence message like this: "Stop playing hard to get."

My most subjective opinion of your profile is that perhaps you are giving to much information up front. Think about showing vs. telling... Also, perhaps the "I'm not a nice guy" is a bit too much.... I'd make all my sentences positive statements.
