I can tell you I am not the biggest enthusiast of Twitter, but I have to agree with this chart. Of the people I see on Twitter, most of them seem to fall into the "think they're stand up comedians" section. That or the "misused / over simplifying inspirational quotes" section. Okay that one isn't on the chart, but it should be. If I have to read another "live life like there is no tomorrow" quotes on Twitter... ...I will send you research and documents proving why and how exactly there wil be a tomorrow. So yeah, take that.
Oh and follow us on Twitter by the way. Hopefully we are in the "good information" section, but then again we probably fall into "zombie" section.
