Even now, if you went up to the average person and told them to stop using SHA1 they'd look at you like you were speaking in tongues. The advice means nothing to most people because they generally don't use a hash function, or when they do they don't get to choose which one.
There are some people who could use the information, though - software developers. The only problem is that the ones who haven't already heard are probably making a lot of other bad crypto choices too, so this one piece of advice isn't going to magically turn their cruddy software into gold.
Thanks to Alex Girard for sending this to me.
