I for one love it.

Forums for sci-model builders — where kit-makers can sell you a resin kit made in their garage of Luke Skywalker's "T-167 Sky Hopper" (or whatever).

Electronic kits you would not have found in Radio Shack: Kim-1 replicas, Apple-I replicas, a SCSI emulator for vintage computers, etc.

Fan films that you would have been lucky to catch at a sci-fi convention are now a click away on YouTube.

And never mind how many of these garage kits, fan films, etc, would have even been produced if there were not a niche forum where these could be sold/displayed.
