I just wanted to share this excellent guest essay, by Stefan Schubert & Lucius Caviola, we've just published on utilitarianism.net. As the authors argue: "in order to be effective in the real world, utilitarians should stake out a middle way [between common sense morality and naive utilitarianism]. They should by and large adopt the standard common sense virtues. But in addition to them, they should also adopt six virtues that go beyond the common sense virtues. While a utilitarian life is pretty normal in some ways, it is very different in others."
For readings on utilitarianism, I'd encourage you to check out the whole website at utilitarianism.net. If you read our entire online textbook, you'll know more about the topic than basically anyone who doesn't already have a Ph.D. in the area. For philosophy more broadly, you probably already know about the Stanford Encyclopedia of Philosophy -- it's a fantastic resource, though the entries vary a fair deal in how accessible they are to non-experts.
For chatting about the topic, you're welcome to reach out but I can't promise that I'd respond. Your best bet is probably to follow some philosophy blogs (and participate in the comments sections), such as PEA Soup, Fake Nous, Hands and Cities, or my own Good Thoughts. You might also try a smart philosophy student, like Matthew Adelstein of Bentham's Bulldog, who is likely to have more time and so may be more open to discussing topics that you propose, or doing some kind of online reading group together.
Good luck!
