If by a good chunk you mean <0.1% of their content, I agree. The majority of Reddit users did not care to migrate, and many that did migrate didn't delete their old content
I see the point but I'd personally rather start asking the questions, whose answers have been deleted off of Reddit, here to build up a new (hopefully fireproof) Library of Alexandria.
For me personally for mundane-ish questions, searching the web-archive for a snapshot that still had the answer is too much a hassle and not as future proof. If a snapshot of that specific question even existed in the first place.
I do have to say that I've seen such replaced comments at least 3 times in the wild by now which is way more than I expected at first. It's a loss for sure but I do have to appreciate that some people actually followed through to such an extend.
Good, the less traffic Reddit gets the better. If someone has a question then the answer can get reposted, or WayBack can be checked. So long as Reddit doesn't get the web traffic.
Yeah that is a fair point, hopefully as it seems like people on Lemmy & Kbin are more active than Reddit users, we should hopefully see these communities grow a lot more to the point of passing Reddit numbers.
