Although I may not be the oldest person on this wiki... I can imagine what it is like from when the wiki was created, to what it is now. Here's my Point of View of the timeline:
First Created: It was not much of a wiki. still in need of members, low amount of people, and not much information. It had little pages, and little popularity.
Wiki Rises: At this phase, the wiki is now a normal wiki, with enough users on it, and a few trolls that were there to ruin most articles. Then, with new games of BattleBears come to life, and a few major updates, the wiki takes an interesting rise.
Wiki starts to head towards downfall: Now at this point, things get darker. More trolls come, more negatives, and a few members leaving. This is where people become inactive, and loses popularity. The games and updates also become more inactive.
Wiki Near to Downfall: The wiki is near to become failed, and an empty wiki. With few users now roaming the wiki, there is little popularity and excitement anymore. The wiki is near to Downfall...
It is almost the same as Near to Downfall now. More people leave, and become inactive. Some are at the brink of retiring forever also. And one just did. Applergamers. Now the wiki is near to the end... for a few more months left now.
Of course, this is almost every wiki might encounter now. Be it gaming, reading, movies, etc., they will come across the same fate as ours. It gets popular and then people start hating. I might be a derpy jeff, but I am really serious about this. If we want a good wiki, we have to keep it alive. That's our responsibility to monitor everything on the wiki.
