Last week I was creating a slide for a workshop aimed at academic staff and research Postgrads, entitled Twitter for Improvers. On the slide I was attempting to explain what worked with hashtags, and what didn't - for example putting in punctuation causes the hashtag to break.
Then I thought, it would be better to actually do these as tweets (show don't tell!) - I did so just with the idea of print-screening them and deleting them, but lots of people joined in with replies and RTs and I added some ranty opinions on hashtag use as well as the factual and logistical stuff...
So here, in Storify form, is what works and what doesn't: The Laws of Hashtags!
(If you can think of any more leave me a comment.)
