I remember this was discussed some time ago and even back then my opinion was that retarding the site for the sake of Amiga web browsers did nothing to spur development, and nothing to make the community look like it had moved on from '98 when people seemed to genuinely believe the Amiga was due a comeback.
Is anyone still under the impression that's going to happen? Amiga is retro, and it's freaking awesome, and if people want to browse the web on one, have at it. But it's their battle.
Now, as ever, I think that Amiga.org should serve the classic Amiga community in the same way the C64 sites do, or whatever. No-one at those sites worries whether they're going to render okay on a Spectrum.
One doesn't honour the dead by mounting the corpse in plain view.
