Not Noobs but new people. @Radius55's journal got me thinking about what I consider to be Newbies to the RT community. And I finally nailed it down. First year users to 2006 are the old farts and 2007 to 2009 I think of as Veterans of the site. Both of which I lump in to one category of original users.
2010 to 2012 are the 2nd gen users and younger but experienced users. User after 2013 are new folk. And anyone after 2015 are wet behind the ears newbies.
Or to put it in a more archaic vernacular: The 4yr high school 8 yr grade school system than virtually no one uses anymore.
First yr to 06 Seniors.
07 to 09 Juniors.
10 to 12 Sophomores
13 to 14 Freshman
15 and beyond Grade school
Don't ask me how I came to this decision as it is 100% arbitrary and has no basis in any kind of logic.
4hrs later Edit: Now that I think of it there is only one bit of logic behind it. The mod point trading for Karma Lvl abuse of the OLD site. What I call the mod point wars. If you were around for the "Oh I'm Lvl 45 and you're Lvl 12 so shut up Noob!" arguments in the forums even though the Lvl 12 had been here for a year longer than the mod point hacking 3 or 6 account Lvl 45 user.... Then you are OLD as dirt as far as the site is concerned. That included many of the Jr.'s as well as all of the Sr.'s in my opinion.
