Depressing, isn't it, the state of the web these days?
Back in the good old days you'd request a document, and the server would send you a document to be viewed. The web used to be the structure formed by hyperlinks between these documents, edges in a sea of information. Now, you ask for a document but the server gives you an application to execute. Ha! It used to be that only fools would run everything they ran into on the web, that's how you got viruses. Those applications could do anything, after all, and you wouldn't know what until it was too late.
How did it come to this? And is there any way to turn back the clock? I don't know, I truly do not know, but I've found that not participating in the advance of the technology will only leave you behind, it's not a method of changing the world. While turning my entire website into a huge ugly webapp where the urls are routed on the clientside might be an atrocity to the foundation that the web of yesteryear was built on, avoiding it like a plague would paint me as a neo-luddite instead. This is the web now, like it or not.
If I could change the trends of the entire web with my own hands, I certainly wouldn't be doing this, but perhaps the web of tomorrow will be a web of applications and open APIs. That certainly has good side to it, too, although the privacy implications are terrifying - even more so once large media corporations insist that the owner of the computer has no business tinkering with what they're executing on the machine...
