I've learned that coming to the forums can be a much more pleasant experience if you skip the threads where someone is whining about not getting what they want when they want it, and instead open the threads where there are questions being asked, and try to answer them when you can. Leaving the baiters and the haters alone has greatly enhanced my experiences here. (I did fall off the wagon once recently, but repented.
)
One of the other things I've learned is that going to the forums can be like going to the mall. I wish I'd learned this truth earlier. I rarely go to malls any more, as I usually double the average age when I walk in. (Sometimes I think I double the average IQ as well, but that's because I carry some biases. That's another story.) But the main reason I don't go is because I see stuff that I didn't know existed, and suddenly can't seem to live without it.
How does this apply to Logos? Well, if I could trade back all the resources I bought because other people in the forums thought they were the best thing since, well, the Bible, I could buy a few resources that I would actually *use*, as well as some lunch money to boot.
What I'm saying is, be careful when folks on the forums are raging (in a good way) over some new resource. Don't buy it unless you'll use it. Even if it is on sale. Way on sale.
A great example of this is the recent Oxyrhynchus Papyri. It was on CP for a LOT less than it was going to sell for in pre-pub or even with academic pricing. Tempting, right? I mean, it closed on CP for $120, and it's now $249 on pre-pub! What a bargain it was!
But remember this: many Christians won't even read their Old Testament. What are they going to do with a collection of shopping lists and reminders from a well in an Egyptian city from a fifteen-hundred years ago? I grant that there are a few specialists for whom this resource is very valuable. But chances are, you are not him (or her). What if you saved that $120 and put it toward that commentary collection you keep wanting (and which you'll actually use)?
Buying something you don't need at 50% off isn't a method of saving money. It's a method of going broke more slowly. (That's also true about shoes, ladies, and tools, guys.)
I now have hundreds of resources that I'll never use (mostly from buying collections to get a single book I wanted, which is also dumb, now that I think about it). Some were because of the hype in the forums. I wish I'd not jumped on a few of those bandwagons. One good thing though: My heirs won't have to make a trip to the dumpster with all these silly books they don't want. Oksie rinkus what? 
Just my two euros worth and my activism for the week. HTH.
