John, I think you'll find that on a forum aimed at "serious photographers" the "bias" will be toward "serious photo processing", meaning relatively complex programs (like Photoshop/Elements) that have the capabilities we need to get the most out of our photography.
But, we all had to start somewhere, and for many of us that was with simple software, often what was given away with a camera, printer or scanner, and gave us simple tools to quickly and easily enhance our photos to some degree and then to print or use.
As you've seen, early editions of Photoshop Elements is one of those programs that is often freely distributed simply because, despite your first impressions, Elements is quite easy to get up to speed with compared to other popular photo processing programs.
But still, sure, things can seem overwhelming.
So, what is it that you want in a simple editor? If you are using Windows, you can open a basic editing program such as Paint, or a couple other options that will allow you to do some things -- crop, resize, some basic adjustments to tones, etc. Be aware, though, that the more you want to do, the more complex the program will need to be.
Another tactic would be to do an internet search of what's out there. I just did a Google search for "free photo editor" and came up with this page:
http://www.google.com …urceid=ie7&rlz=1I7ADRA_en
"Free" will typically imply "simple", although some programs such as the Gimp (which is on that page) are the results of some serious programming in the open source community to come up with alternatives to Photoshop. But, if you take the time to download and try out the various offerings, you'll hopefully find some that satisfy you.
You say you are unhappy with Picasa, although that is actually one of the simpler programs out there, so it may take some time of finding a fitting editor and learning what you need to learn to get up to speed. But in time you might find like many of us here that processing our photos is a rewarding task, and we enjoy the fact that a bit of processing can really enhance the appeal of our images.
Hope this helps some!
