Why do you post here? Other than Learning, networking or sales?

[Cal C.]

For those of you who market (sell), learn or network I know why you are here, but I'm curious as to why others do?  Personally, I post to learn somewhat but more importantly, I post to prevent others from making mistakes similar to the ones I made when starting out. 

Also, I guess there is a bit of guilt involved since I realize that some of the properties I have bought over the years likely came from investors who lost it all and were foreclosed on.  

I know that going forward into the next downturn, I will be picking up more properties from investors and it will make me feel slightly better if I know that I tried to warn people about getting over extended or making bad investment choices.
