I see a lot of tweets saying that people don’t blog anymore because of micro-blogging.
Keep tweeting but and come back to blogging as well. On a blog you can build a longer lasting impression where a tweet would have past someone’s time-line even before they saw it.
Blogging is more personal since you don’t have to compete with all the other tweet noise. People who follow your blog is more likely to hang around and comment on a few posts, micro-bloggers are jumpy, trigger-happy clickers who will just scroll away you well crafted short message to the world.
