As mentioned elsewhere Homestar Runner is still around and not doing badly. The Wiki, however, is severely starved for resources, it always takes a long long time to load for me.
It wouldn't be difficult to make Lenovo laptops more repairable. I've had two, and both required taking the whole thing apart to replace the keyboard, the part most likely to have problems. I hate that about them.
Mobile devices tend to be much less versatile than PCs, mind you, and on purpose, due to one of Steve Jobs' most misguided apprehensions, that it'd be a good idea to hide the filesystem from the user. (Cue someone somehow claiming that's Good Actually in three, two, one...)

One thing that still exists is WWWF Grudge Match, a likely inspiration for MTV's Celebrity Deathmatch, a crowdsourced humor site where they put different pop culture figures against each other in textual battles and people contributed their takes and votes on who would win.

TimmyBigHands, short-lived humor magazine from the Mystery Science Theater 3000 people shortly after the show folded the second time.
The Sci-Fi Channel's website and MTV.com, both started with the hopes of becoming a substantial part of the World Wide Web by getting in early, then shuttered when owners lost interest or believed the lies that social media was where the only thing that mattered any more.

I have to ask, is the software preservation 4am, who cracks the Apple II disks? If so then hooray, thanks for being so great!
