When I first started writing seriously, I was amazed by how supportive the writing community out there really is. People going to each other's book, signings, plugging each other's books, websites--it is all so edifying.
I know for me, I love helping people, so anytime I come across a new writer who needs helps, I'm happy to point them in any direction I can. As far as I'm concerned, you can never have too many good books on the shelves, too many good authors out there. Plus, I strongly feel in the "pay it forward" concept--that if you've been helped, you have a responsibility to go forward and helps someone else. People might call it good karma, but I call it just being a good human.
How are some ways that you help other writers? How much time do you invest? Do you go to book signings, buy your friends' books ...what else? Comment on blogs, friend people on Twitter, Facebook--I feel like I'm still learning, so I'd love some tips out there.
