Basically an enhanced about me but with business capabilities as well.
First thing I do is that I will ask you out for coffee. Straight to the point, I just think that if people can meet on the street and go out after that, a meeting at a coffee shop with someone who expressed interest in you on this website is not that big of a deal.
Sincerity is not something that you can feel online. Honesty is not something that can't be portrayed through a website. So take it or leave it.
I am currently taking a diversity in the workplace course and if you want to talk about any of the isms, let me know. I like having serious conversations over coffee.
