Science communication seems to be getting more popular; that or as usual I’m just more aware of it so that’s what it seems like.
I do think, even if it’s not more popular, it’s a bit different. Science communicators of the past were often Robert Winston or Carl Sagan types; while often brilliant, typically not that inspiring to many groups of people, being fairly posh middle-aged white men.
If you’re interested in outreach (trying to get people interested in science generally) then have a think about coming to ThinkCon in March. http://thinkoutreach.org/ was set up by friend of Super-Duper Woo-Fighting Duo (with capes!), Andrew Holding.
I’m dabbling in it a bit myself – both on this site (see ‘communication‘ tag and the series of posts I did on the BSA SciComms conference last year) and elsewhere – a recent example being the following video. Don’t laugh too much.
