Divorce or Marriage troubles broadcast on the Internet = Fail.
Divorce or Marriage troubles Publicly consoled through Internet sympathy = Fail
Divorce or Marriage troubles Publicly consoled through women (or female profiles) on the Internet = Fail.
Having made ALL of the above mistakes myself I shall say this: If your marriage is on the rocks, don't tell anyone until it's really broke (as in one of you moved out and took the dog with you).
If you are picking up virtual poontang, keep it discrete because you never REALLY know, do you?
Don't fall in love until you see 'em face to face and evaluate their bedroom skills "for real". (btw, this applies regardless of sex, male, female, hetro, bi, homo, whatever).
Falling in "like" may be unavoidable. Nothing risked, nothing gained.
