@KLA2010 Just noted “Open science enthusiast” on your profile. Have used that term for myself a few times.

140 is too short, so …… I was going to use ‘TweetLonger’ but decided not to do so in the end.
As to who first came up with “Open Science Enthusiast”, we’ll never know and frankly, who cares…. To me, in short, it means “Citizen Scientist”.
I was present at Scotland’s 1st Open Knowledge (possibly 2nd) event (in Edinburgh back) in 2012. 
At one point, those present were asked to describe themselves in just three words. Off the top of my head, I went for ‘Open Science Enthusiast’. I was the only one to do it in three words, so that was my starting point. – Since then, I’ve used it elsewhere even including peer reviewed papers such as:-
Buckland, A. et al., (2013). On the Mark? Responses to a Sting. Journal of Librarianship and Scholarly Communication. 2(1), p.eP1116. DOI: http://doi.org/10.7710/2162-3309.1116
The term has been used elsewhere, e.g. here by Dr Marcus Hanwell @
I predict that high on the list of many open science enthusiast’s new year’s resolutions will be the education of both established and future researchers on the importance of openness, licensing, sharing, and reproducibility.
