You are so full of it. There have been addons, vent (or voice chat of some sort) and ElitistJerks almost since the beginning.
1. Addons
DBM -
http://www.curse.com/addons/wow/deadly-boss-mods Listed creation date: April 2008, which is mid/late TBC.
Recount -
http://www.curse.com/addons/wow/recount Listed creation date: August 2007, mid TBC
Hell there are even some that were created before TBC like Auctioneer.
So unless "Back in the day" only includes vanilla then I call BS.
2. Ventrillio/Voice Chat
Vent was initially released in August 2002 which was before wow was even originally released. Vent has been used in wow since the very beginning. So again... BS.
3. Elitist Jerks
They have been around as a resource since mid BC - See ferel thread here started in Oct 2007:
