Well, since you asked, and I'm glad you did :)
As a green newbie, I became a member a yr ago and recently rejoined after letting it lapse, missing the rejoin incentive, but at the time it just wasn't feasible (there was a good chance I was going to be laid off from my teaching job). I first have to say that I love this site, I have learned so much! But truthfully, most of that knowledge has come from the forums. I recently went with a group of "non-enlightened" packers and was stunned to see the weight they were carrying! I was eyed suspiciously for my 20 lb total wt. pack. I had to hear more than once that my Steripen was ineffective and unreliable. I also got the same treatment about not wearing hiking boots. It was hysterical really. I didn't preach about UL gear to anyone, but just laughed to myself as on the last day of the trip the same negative ones were complaining about their knees and feet :) I on the other hand felt great...but I didn't rub it in.( I'm a nice person:))
Anyway I will recap some of the posts that I can relate to. +++1 on all.
Chris Wallace: Maybe a recurring column from people like Ryan and similar others? Mike C.? Andrew Skurka? Dave C.?
Doug Ide: Even if you have an editor culling great blog posts and posting them here (with permission, of course) with links to the original blog, you could easily and cheaply add some stellar content. Dave Chenault's and Roman Dial's blogs are an exemplary example of this, for just two. There are many, many others. You could start a new 'blog' section where you add such posts - I think it'd be popular.
Daniel Allen: Maybe make the SUL forum for members only? Those zealots will pay almost anything, right?! ;-) LOL!!!!!! I know that was said tongue in cheek, but it was just stupid funny.
Kat P. If my yearly membership can help keep this site going, that is worth it enough for me. I don't need any extra perks compared to non members.
Mary D: (1) A larger number and wider variety of articles each week, about techniques and trips as well as gear.
(2) An easily findable list of articles for beginners to which we can refer people just starting out, many of whom post on other forums with which I'm involved. This particular aspect, IMHO, should be free as a public service. They should be updated every few years. The old "Backpacking 101" is a prime example--in fact, just updating that article (10 years old now) would be sufficient. Having this public service base to which to refer beginners would bring in a lot more members here--consider it advertising!
Matt Tallman : In light of the time I've spent on other forums, which actually have useful features like a search, the ability to easily quote/reply to other users, doesn't require someone to insert a goofy subject line to reply, allows links, has a functional private message system, etc. the list goes on.
Yuki Maki : Trip reports + pictures = crack for outdoor junkies.
Gerry Volpe: I still think this is a top notch community of people and an excellent resource more than deserving of financial support.
Aaron Benson: I "heart" BPL, so please be careful - your Customers are talking. ;)
Lastly, I have found this site, especially the forums, but articles too, to be invaluable to someone just getting into the sport (the right way) and I do spread the work when people ask about my gear. I hope it will continue to thrive.
