1) Comment on other's blogs. Especially if they are already commenting on yours! When people comment on my blog, I feel validated, noticed, appreciated, cared about, and all the silly things that I thought only mattered to me in high school. Well, it's not just me. Everyone feels that way. So take the time to say hello to other people. Sometimes all we have time to do is read and walk away. But if you can say something, it will invite people to wander over to your blog and say something back.
2) Ask a question. Give your readers something to think about and respond to. It will help make them feel like they aren't just listening to you, but you are listening to them.
Along those lines...
3) Comment in your comments! Your commenters are talking to you. They don't really care if other bloggers read their comments, but they want to know you did. So say something back! Responding back in the comments will help it not be a one-sided conversation.
And finally, the biggest thing for me:
4) Make it easy to leave comments. Recognize this?
This little splattering of letters annoys the heck out of me. Are we really afraid of spammers, or do we just not know how to turn it off? I can't tell you how many times I've posted a comment on someone's blog and hit 'post,' then closed the screen--just in time to see a little box pop up wanting me to enter in those lovely letters. Oops. Too late. I closed it. Do you think I take the time to go back to that blog and retype my comment? I never have. I just groan, feel frustrated that my important thoughts won't be read, and move on.
So, in case you didn't know about those little letters, here's how to turn it off: Click "Customize" up at the top of your blog. Click "Setting". Click "comments". Where it says "Show word verification for comments", select 'no.' You might not even know you have it on, because it doesn't show up to the blog owner. (And readers, if mine ever defaults back somehow, please please tell me!) Don't forget to save your settings!
Well, now you're all set! Let the commenting begin!
Did I forget anything important? Maybe some of you read the blog I did. Anything else?
