We should all remember that we are visitors in a private room here at LULA (as in other fora).
Actually that's an unduly deferential attitude towards sites like this.
The success of Lula, and sites like it, is not just due to their content, but their readers and contributors. If readers like the content they tell others and drive up page views, without that peer recommendation the site never can become popular enough to be self supporting.
Similarly without all the contributors to the forum, it would just wither and die. It's worth considering that it's just a few hundred members out of the 45k registered that make major contributions to that content, they have a stake in it by virtue of their own freely given efforts.
So we have a right by our support and contribution to comment on where the site is going.
For me I agree with the OP that the quality of the site has slipped recently.
Originally most content came from Michael himself and always seemed to be aiming high, both with respect to technical articles that had real world usage at their core and with great photography.
As the front face of Lula has used more articles and photography from other authors, that standard of aiming high seems to have slipped. Commercial interests now seem to drive things more and mass appeal is more important.
I find it a shame, I always liked that Lula was a place for serious, considered work and not somewhere where people posted pictures of dogs with hats, there's plenty of other places to have "fun" if that's what you want.
