I have attended several conferences in my life. Some inspiring, some boring, some well organised and some a terribly mess. I have also not attended a lot of conferences in my life. Either due to lack of funding or lack of time. Conferences which were not relevant enough or where only one session was really interesting. I have sometimes wished that I could use some Harry Potter tricks and through a portkey transport myself around the world to participate in one session and then hurry home again. Or use a time-turner so I could go back in time and not miss out on a parallel session to the session I chose to attend.
Portkeys and time-turners are to my knowledge still not widely spread, but then the next best thing might work: Twitter. Conferences are a different thing when Twitter is involved – both for the good and for the bad. My first conference Twitter experience was at Science Online London 2011 and I must say I was quickly hooked.
