Re: Have you been into PDFs long?
Also unlike FB, there's a record here of the changes in the hobby. I bet it would be fun to look at really old threads about, I don't know, viv size recommendations from fifteen years ago and then some recent threads.
I know I bump into old threads about how some frog (vanzolinii was the one I noticed lately) is really hard to get a hold of, and now they're quite common in the hobby. It gives a nice perspective to a newcomer on how things got the way they are.
On a less meditative note, decent off the shelf LED lighting is now the standard, although that may have been almost the case five years ago.
