Serebii

www.serebii.net

Ah, well if it isn't the most famous Pokemon fan website known on internet today. It was created by a person named Joe Merrick, and launched Serebii.net along with a friend of his during 1999, and even today it is still active.

from 1999 to 2010...that's admirable, I would give up on a website within 5 years.

I just like how they show how people can be so committed to their fandom for so many years that they wouldn't give it up at all. According to the year Joe was born which was in 1986, it calculates that Joe started Serebii when he was only 13 years old. And now he's attending university, but whenever he has the free time he updates the website whenever he can, he also has fellow online helpers that also contribute to the website.
It's amazing how so many people can come together and be devoted towards one specific thing for a very long time.
