Micro-blogging is a form of blogging that allows users to write brief text updates (usually less than 200 characters) and publish them, either to be viewed by anyone or by a restricted group which can be chosen by the user. These messages can be submitted by a variety of means, including text messaging, instant messaging, email, MP3 or the web.
The most popular service is called Twitter.
BLOG i 360:
BLOG i360 is a marketing platform that was built originally on WordPress but has grown way beyond it. On top of that, they have a more robust content management system than WordPress's basic "Pages" feature. The key word here is "automation". This does many things automatically for us, which we may have to do manually in other blogs. At $39 a month while they're still in beta (they say they're eventually going to $79 a month, but founders lock in the $39 price), it's a lot pricier than basic hosting, but how much is worth is your time? Only downside is that you have limited flexibility with the design, so if you have a very specific look you're going for, this may not suit you (yet).
Microsite:
A microsite, also known as a minisite or weblet, is an internet web design term referring to an individual web page or cluster of pages which are meant to function as an auxiliary supplement to a primary webpage. They are typically used to add a specialized group of information either editorial or commercial. The main distinction of a microsite versus its parent site is its purpose and specific cohesiveness as compared to the microsite's broader overall parent website.
