Micro-Blogging is still going strong and there are a ton of them popping up for every niche and theme imaginable. Some of them allow you to get do follow links so this does fall under the general link building topic, but they also allow you to increase your reader base and grow your website. The stats I’m going to use to rank the sites will be based on Alexa ranking,(unique not site wide links counted) backlinks counted by Link Diagnosis, and Google Page Rank. If anyone has a site I missed, or even a new one that they’re going to release then you should leave it in the comments or contact me. I like to mention only use these sites if you plan on using them for what they’re intended for, and not just spam them to death. I understand people use micro-blogging services do promote their products and that’s fine, but don’t overkill it.
