... Official sites have the clout and they may be formatted in the proper way, but the contents just don't fuel the imagination, at all.
That's probably because fan-run websites and fan-made artistry are generally built over long periods of time out of a love and/or passion for the subject matter. It means more to the person doing the creating than, say, a corporation that wants something done as quickly as possible without investing a lot of time and money in its creation. This maximizes profit margins but oftentimes provides less-than-inspiring results. On the rarest of occasions, you will have someone with fandom-level passion who is being paid to do something with such skill and ability, that they can knock out some top-shelf work quickly and efficiently that also appeals to other fans. I noticed this being the case a lot more during Trek's heyday back in the 90's. It fizzled out in the 2000's and is pretty much non-existent in this decade. In many ways, I think that most people have stopped caring about...well...everything. Bleak times we live in these days, my friends.
