SundaeGirl Omlet is a company that is aimed very much at people who just want to keep a couple of chickens in their back garden, and have no idea where to start. Nothing wrong in that, and they were simply in the right place at the right time, when small-scale urban chicken keeping started to take off (and to some extent they caused the take off) in 2005/6 or so. I think at that point the forum was primarily filled with inexperienced urbanites, and I never really used it, as I'm not an eglu owner, and I was happily using other forums at that point. However, having had a look at the forum, it seems as though the inexperienced urbanites have since become more experienced, although they don't quite share my slightly more no-nonsense they're-not-dogs-they're-chickens-so-treat-them-as-such attitude towards pet chickens (the thread about whether or not a dead hen should be shown to the others so that they know she's dead, for instance
)
I have found the community feel elsewhere (BackyardChickens in particular, although I never really got my teeth in the PP forum) - it's just that it's often not immediately obvious to a new forum user. BYC even has meet-ups for its members. The members on there can be surprisingly useful, and I know that on several occasions (either through specific diagnosis, or through me learning things that preventing problems later on) the users there have saved my hen's lives / expense / faff.
I think you're probably right that the old-school (yes, often old men - I know I've come across a few, erm, characters when buying hens - such as the one who told me, proud as punch, that they even had running water now - no electricity, mind!!) fanciers / breeders can tend to be a little technophobic. In my experience, they usually only take to the internet when they have birds to sell! However, people who keep them for pleasure / small scale meat / egg production are more likely to take to the internet, and can often be just as knowledgeable, and less likely to recommend medicines / insecticides that were banned 10 years previously for being carcinogenic (or wringing their neck, lest they spread disease, as the response to any sick hen!).
