Therealityis, if people didn't "move on" and start their own sites, the WWW would be a very small place to hang out.
People started a site about cornsnakes. So What? Who cares why they started, how it happened or what motivated them. The fact of the matter is, it is merely one more resource available to anyone willingto visit and read.
There is nothing juvenile or immature about leaving a site and starting your own because you don't agree with the way things are done. In fact, it is the basis for the internet. You can't find a site that you like...start your own. MAKE a site that you like. It is the very reason behind the tremendous and rapid growth ofthe World Wide Web. It is the beauty of it's nature. There is a place for every person to openly and publicly display their talents, desires, and interests, within certain reasonable and legal limits. They can also bitch, moan and gripe if they want to.
What is truly "immature" and "juvenile" is the rampant judgmentalism. What is truly ridiculous is how people are being judged "juvenile" because of a personal choice. It doesn't matter what the argument was, or what the rationale is. A personal choice was made to start a new website, and to run it the way THEY wanted it run, not someone else. So Be It. It is certainly less juvenile than calling people names because of it...
