It is part of what I like to call the Photoshop Phenomenon. Before computers, scanners, and Photoshop, people with actual artistic talent could draw and illustrate. Now, however, the simple to use Photoshop program will let anyone who can point and click draw an wonderfully detailed digital picture.
There are two things I see in this, the first begin positive. Photoshop has opened up a media available to all of those with little actual drawing skills, so that even they can represent their imagination via an image. However, it's taken away from traditional artists, who suddenly aren't all that a big deal since anyone can now create art. For example, take a look at Deviant Art. Sure, you get great looking digital pictures and artwork, but there's is so damn much of it, and most of it is by people who couldn't even hold a pencil to save their life.
now, how does this apply to anime? Simply, anyone with enough money to put down for animators and equipment can spew out something that is technically anime. Often, this type of anime is bout in numerous quantities by "fanboys" and "fangirls". However, most of it has an unintuitive or cliched storyline, as well as artwork that you see copy and pasted from other such anime. In short, with globalization and capitalism at an all time high, it is quite easy for someone with little to no talent to take their (for lack of a better word) ideas and to apply them to such things as anime.
Let it be known that I do not hate those Photoshop people, but it bugs me a little that traditional art is on the decline.
