If this slips into yet another debate, so help me god, I'll post anthrax to your house. You wanna debate go D&D (or alternatively jump off a cliff).
I don't think it matters if your gay in your career anymore, as for in society not so much. Gays have self inposed a want to stay in gay communities, sortof as a safe guard. The main argument would be, if I were to go with a bf to str8 nightclub and start snogging, would anyone care? Personally I've done it, people don't care, but it doesn't stop people being scared something might. Apart from that, I don't think it makes a difference. In a couple of years time (I think), new legislation comes into force which prohibits discrimination on the basis of sexuality. Honestly I think homophobia will fall out of fashion and people will eventually accept that it happens. Thats probably a very round about way of answering your question. Oh and finally, don't feel pressured into coming out to anyone - it's your life and you tell people when your ready.
