Annoying? Poor usability? It looks like a button, reacts on mouseovers, and would totally fit in some game's website. Besides, it is not the point here.
…takes 41KB, and does not work on systems without Flash installed.
What is his point? Flash rules HTML5 drools? Who cares. If a developer wants to use Flash then he can use Flash. If he doesn't, then he won't.
My thoughts too. While that might be a silly button to have for many sites, it looks like something I've seen in more than one video game menu. So, it's not without merit.
