Question - How different is the present CC from the one of 2009?
Much different. Back then there was no Youtube channels. no bible bots. no posting images in chat.
There was also an experimental "video wall" similar to Google Hangouts, where everyone's video would be on at the same time. Revolutionary at the time considering there was no such thing as google hangouts or g+, etc.
There were also fewer channels, so most of the chit chatting would be in the Lounge or the BibleStudy rooms... Yousing was added cause people kept wanting to play guitar on the cam...
That's another trend, go look at google trends for guitar... It would seem that we're in a decline and no one wants to rock anymore.
Let's take a look at the chart: (Courtesy of Google.com)
Notice how each year the search for "Guitar" would peak around December (just in time for Christmas!)
Guitars also used to peak in the summer month of July, as kids are off from school and wanting to start a rock band...
Unfortunately... The kids have been swamped with bedroom musician digital unst unst unst music (Which is also great), but the desire to be a rockstar with a rock guitar is on the way out as a culture...
