I've mentioned a few times on here that Twitter / social media are becoming ever more important for writers. Not simply because you can market your writing and increase your reach, but because of the community aspect; the shared knowledge and experience from professionals and colleagues alike. Never before has there been such ease of access to editors, authors, and publishers, all with fantastic things to say and, yes, years of experience under their belts.
Perhaps the best hashtag to follow is #PubTip - a sure fire way to get timely, insightful and - most importantly - practical advice from agents and editors. It's a constantly moving conversation, and you can jump in at any time. I spent a few minutes searching through, to bring just some of the posts to you. Enjoy!
