As a lonely man, who has never been in a relationship in his 37 year long life, this is something I will stay faaaaaaaaaaaaasaaaaaaaaaaaaaar away from, I know that could easily get hooked on these services.
I keep a mental image of an attractive woman in a business suit and a nametag with the company logo on it to remind me of what it actually is.
You may be speaking toan attractive avatar, but its just a corporate machine that want all your data and have convinced you pay them for the privelege
