Microblogs are platforms for distributing bite-sized chunks of content.  By limiting the length of a post to just a few words, the posters can get a message out extremely quickly and concisely, and readers can take in a huge number of posts in a short amount of time.

The most popular microblog platform has always been Twitter, which has been the perfect space for up-to-the-minute news announcements, comedy one-liners, and excessive and unnecessary pictures of people’s lunches.

Other microblogging platforms include:

Tumblr
FriendFeed
Plurk
Indenti.ca
Google Buzz
