InfoGalactic is good for several reasons:

• uncensored
• deep encyclopedia
• classic familiar wiki format (Other wikis change their layouts, CSS, or how they present articles - all kind of annoying)
• pretty fast response (WikiSpooks on the other hand is sloooooow)
• not corporate (ie Wikipedia, the sister projects, and WIKIA have the same owner)
• all but one of the people have been decent
• receptive to non-encyclopedia wiki-based projects

InfoGalactic is bad for several reasons:

• the encyclopedia is a mirrored fork so a Wikipedia copy is the foundation
• many of the mirrored articles are long out of date or haven't even been copied yet
• the mirrors don't copy the page history or the talk page and it's history
• A BIG ONE: there is no distinction between a mirrored WP article and an article that has been modified or an entirely new unique IG article
• the appearance is almost identical (they could at least ad a touch of colour so you know you're not on WP)
• there is virtually no community or use of talk pages
• a lot of images are missing and/or go missing
• there is virtually no tech support, though it's pretty good and stable
• there is no roadmap or plan
• A BIG ONE: there is no community so there is no discussion so we cannot agree on anything so there is no regulating things. Specifically, on WP there is one corporatocracy "neutra" (ha!) perspective, meanwhile on IG I've tried to get folks to come together and at least create basic labels to add to articles or sections. Sure there's a LOT of grey area, but for the most part you could easily keep the number of perspectives to a minimum (ie. Wikipedia perspective, SJW, Right, Alt-Right/Libertarian, Progressive/Green, Anarchist, Truther/Conspirophile) Let everyone have a say and use the labels as you see fit so the reader doesn't have to do further research to come back and guess your angle or game your pushing.
• the "Galactic Boardroom" (their tearoom) is full of more of my suggestions, ignored : https://infogalactic.com/info/Infogalactic:Galactic_boardroom
• here's how active it is : https://infogalactic.com/info/Special:RecentChanges
• User:Froglich is a right wing asshole who can't see that we actually have waaaaaaay more in common than he can recognize. His articles are on good topics and does pretty well but there a deep bitterness caused by his blind belief in the left-right paradigm. We had some wars but then I stopped punching myself in the dick and stopped responding to his crap. And he stopped.
• One thing we had issue with I won as you can see here: https://infogalactic.com/info/Chomsky_(disambiguation) where Froglich wanted his conservative satire slander article first and to delete the WP version. I insisted it go to the disamb page to let the reader decide what perspective they wanted.
• They set it up so the front splash page displays alt-right news and I'm not aware of any way to submit suggestions.

This list looks lopsided but the freedom from censorship is the biggest draw followed by the ability to wiki beyond the encyclopedia.

So "Down The Memory Hole" is your local "franchise"/instance of the greater PeerTube community/project. It's starting to sound a lot like Holochain.

You said "video being findable if it's mentioned somewhere else I guess" which made me think of something, similar to your issue with loosing videos in your playlists. Most of the videos on SaidIt are on YouTube but one day may not be there, so while SaidIt is still small it'd be easier to mirror those videos onto a dedicated SaidIt>YouTube>PeerTube franchise so they'll never be lost. A bot could go through and change the code from YouTube to New.PeerTube whenever a transfer is completed. So too, it'd be MUCH smaller and likely easier to scrape all the links to other sites, PDFs, images, music, etc. and then bot recode. I don't know if this would be a copyright nightmare, but I think it'd be great not to rely on the InternetArchive, which is in San Francisco's Presidio area, which once was (and still might be in part or whole) military land. It's actually quite a pleasant place.

I wrote up my Wikipedia experience. (I think everyone at IG has had one too.) It's not very spectacular but you can read about it here: https://infogalactic.com/info/User:JasonCarswell#Censored.2Fbanned_from_Wikipedia_for_one_year Which reminds me I need to offload from RationalWiki (not very rational) where I floundered for a month or two between. They are skeptical of God but that's it. I tried telling them that the CIA created and funds ISIS. That did not go well. Also in that collapsed section are a lot of links to half started half ideas I should clean up, remove, or integrate. Don't waste your time with them, or do if want to. It's public so I don't care other than there's nothing to be proud of.

Ya, Steemit is sketchy from top to bottom. But it's something and it sort of rewards, if you're a whale. I've never been in it for the money, though I'll never say no to it. Some folks need it and some folks want it. I'm glad I don't accept and endure that burden. I hope that someone can build a Steemit alternative on IPFS with Filecoin or some other crypto and DTube can be free of Steemit if it chooses or be a cross dual platform thing.
