I don't think they mean with two people - I think they mean maybe 10. 10 people with 1,000 tbt each still is 10k. Plus, you can gradually increase it as you go - getting paid from one person monthly, then use that to put it back in the ABD. If you're determined to get some tbt without killing your hands from typing and forking out a ton of in-game bells, it's probably the best way to do it, albeit, usually wrong.
Would people in real life hand each other $1,000, put it in one account, and fork in the interest?
If you involve 10 people that makes it even MORE work. Honestly, I'd rather just hang out on the boards, and post or whatever. At least then you're here for a reason, you get to talk about the games you like, learn things, share your views, help others, etc.
What's the point of just racking up some TBT, just to have it? :/ I like TBT and collectibles as much as anyone, but I do think there's more to the site than that. Even the people in the Marketplace are having fun at least wheeling and dealing with each other for the TBT. Otherwise, I don't see the point.
