I agree this forum is not as fun as it used to be. But I don't think that's why it's declining in popularity: I believe facebook groups has killed most online forums, as I've seen the same decline in others (surfing, fishing, etc). Easier to use, more interactive, more present / hard to ignore. Web forums were always a relatively small % of overall kiters, but now seem to be nearly obsolete. Mostly a bunch of "old folks" left. I doubt many young newbies spend much time here.
Personally I also find the forum is not as informative as it was, but that's more about my own learning progression: no longer a beginner keener, the honeymoon is over, fully into the "advanced intermediate" plateau ... so now I am clearly in the demographic of semi-grumpy middle agers.
I am at the point of reading maybe 1 thread in 20. And I've cancelled my kite mag subscriptions, tired of the endlessly repeated advertorials and same old ads. And I have been doing more sup foiling and bought a wing ... uh oh.
