There seems to be a love/hate mentality when it comes to Flash. I have seen people create incredible projects, websites, games, etc. with Flash. I am just not one of those people…yet.
There’s also a lot of discussion on whether Flash is a dying breed. It’s just been announced that Windows Internet Explorer 10 will not support the Flash plug-in. This happened similarly when Mac barred Flash from iOS, iPad, and iPhone. Adobe has responded by saying it’s had to adapt in the past and they’ll continue adapting.
All in all, Flash is still relevant for now. Every job I’ve looked at and been interested in has required Flash experience. So for now, I will keep tweening.
