I don't think this discussion has been centered on Baroque at all, considering St. Lukes and I have been talking about Strauss, Wagner, Bartok, and Debussy in addition to Handel, Haydn, Bach, et al. I actually posted a few pages back that I was listening heavily to Chopin (I also added an "especially" in relation to his Nocturnes) and Brahms' Chamber Music. For me, I don't think I innately "prefer" any era, and just tend to play whatever I'm in the mood for. I get bored if I listen to any single composer, genre, or era too much, so I tend to switch it up frequently. So I went from Chopin/Brahms to a lot of Purcell and Handel, now I'm throwing in some Schumann and Haydn.
See above: I don't think there's been an excess of baroque/classical music discussion at all. As for most of this post, I really don't know what to make of it. There's an "obvious superior development of music form" in later music? Really? It seems to me that form began to disintegrate during Romanticism. Wagner, Liszt, et al. were looking to do away with the classic forms altogether, and their influence had practically succeeded by the time of modernism. Classic forms gave way to nonce compositions that didn't have to follow any forms. I'm not exactly against this either, since I love, eg, the hulking monstrosities that are Mahler's symphonies.
As for "post-Baroque music reaching an ever widening audience," I don't know how that's relevant or that it's even true. A composer like Purcell was a celebrity in his day, and wrote music for the theaters in which a great many of the general population attended. Handel's operas and oratorios were immensely popular as well... they weren't just composing/playing for patrons, the royal courts, and the elites. As for such pieces being "considerably easier to play," I'm not sure what that has to do with anything either, but Bach at his most difficult is not easier to play than anyone, perhaps save for Liszt at his most difficult... even then, The Goldberg Variations aren't really "easier" than a purely show-off technical piece like this:

pieces since he was never a virtuoso and had no cause to show off.
