Infographics are a great way to absorb information at a glance and I particularly like this Twitter infographic. It seems the ideal Tweet is short – less than the alloted 140 characters – contains a link for further information and an image and contains less than two hashtags. If you want your Tweet to be seen, ask your followers to Retweet (but not RT) it. And don’t forget to Tweet at the weekends. Twitter is not a 9-5 job.
