Twitter is important for research, learning and revolutionising academic research (I believe). I have used it previously to recruit participants for my PhD research and publicise my publications (to my few but growing followers). While others may prefer to tweet about their personal lives, I prefer to keep it professional although the two get mixed up sometimes. PS: I am yet to tweet about my breakfast.
Some have suggested thinking about twitter as a newspaper, where you can report about serious events but can add fun bits as well (worth trying out). Also, I have realised that its a conversation and not all about me, so I have started to join in conversations hence using the reply functions, and appropriate terminology from twitter glossary more often.
Twitter is also important for networking, emphasis being on ‘networking’. I have followed a lot of people and have had a few follow me back. Nevertheless, I am engaging more with the conversations (I think) and tweeting more frequently. Frequency currently still stands at once or twice a day. I anticipate increasing my follower base by tweeting more frequently and following more people (watch this space).
