The advice makes sense, many times (though not every time, when you get some fanatic who sincerely believes any application in your lifetime is the biggest evil in the entire world, though you gotta wonder how that fanatic got 20 cards with that philosophy) so I wouldn't argue that getting a few cards, letting them age, hopefully getting CLIs, and then in a year or so do it again if it makes sense is bad, it's not. It's smart if you do it right.
I just don't care for all the talk about the 'garden'. I guess, to be honest I don't like the term itself, rather than what it means. Just a personal pet peeve, I'm probably just a weirdo as I mentioned that I don't care for it.
A few of them are hard core about screaming at people for applying. Dude when you run my life and pay my bills, then I'll do what you say, until then I do what I feel like. If you don't like that, well I'm sorry but it's your problem and not my problem. You're always welcome to pay my bills so that changes if it really bugs you THAT much!
That said they do have lots of posters there and a lot of good info, if you can handle the annoyances to get it.
