User:Spatical/list of microblogging websites

This is a list of major active microblogging websites. Unlike the list of List of social networking websites on which these sites also appear, this list shows and compares the characteristics of microblogging websites, such as the maximum post length.

Please note the list is not exhaustive, and is limited to some notable, well-known sites.

I am soon going to merge this data with: Comparison of micro-blogging services. Can anyone edit this page?
