Keep jotting down ideas
That phrase has always remained with me because I thought it was a great way to look at it. You would just throw your thoughts down online even though you may well develop them later on to produce columns or articles for newspapers or magazines. You could even collate all your blog posts, rewrite and edit them into a book. But even if you don't end up doing that they would still be read by others. Blogging allows you to get your message out.
Then along came Twitter, a microblogging service. In a way Twitter is to blogging what blogging is to those traditional media listed above. It can be seen as a "public notepad" for blog post ideas.
Collate the tweets you've shared
So that's another way I use it now. I share stuff with my followers. Then every now and then I look through what I've mentioned and linked to and find some recurring themes. And I'll use those tweets as the basis for my next blog post.
I don't think that this miniaturization process could get any more advanced though. You just couldn't write anything shorter than a tweet that still contained a coherent message or idea.
