There are three places that a blogger should start with when it comes to networking…
Your own blog: You may be the master of facebook, tweet with the best of them, and have more Karma Points on Mixx than one human should legally be allowed to have, but if I try to communicate with you at your own blog, and you ignore me, I’m not going to be thrilled. I’m not gonna care if you’re friends with everyone at Digg if you can’t even take the time to answer a comment, respond to an email, or connect on a basic level by writing meaningful, personalized posts.
Networking via your own blog, is to me, the most important thing you can do to establish important blogger connections. I’ve had potential clients visit my blogs and via communicating with said clients, I’ve landed gigs. I’ve found co-bloggers and guest posters by communicating with readers of my blogs. It’s cool to try out various forms of networking, and you don’t have to answer every single comment, but overall, you can’t forget about connecting with people at your own little homebase.
