In real face to face life, I am with a lot of non-bloggers. People who don’t understand what a blog is, why or how someone would do it. Sharon of In a Minute Ago, has been thinking about it and explaining it clearly since she started blogging 2 1/2 years ago. Her most recent post on the subject is here and she talks about the community building aspect of blogging (among other things). If you are curious about the whole why and how, just read everything she’s posted under blogging– and the comments. It is all very interesting reading.
If any of this inspires you to read more blogs, check out this post about managing your blog reading.
And then, if you decide to jump in and start one, there is a great article on Whip Up about starting a craft blog. If you are not feeling like it is working out the way you had expected, read this other Whip Up article full of excellent craft blog advise.
Good luck!
