It might be convenient to embed tweets, but taking a screenshot and linking the thread is a much safer choice for non-video content. Even with the small number of posts I've made so far, I've noticed deleted Twitter content that I've embedded, and it's often difficult to figure out what was lost and sometimes it is crucial to the surrounding text.
There really needs to be something like Archive.org, but solely for tweets, as well as some kind of repository for video content on Twitter—video footage, like what we'll see at protests and riots can be difficult to find outside of Twitter sometimes. The media chooses not to cover certain events or gives horribly biased coverage of these events, so this sometimes becomes our only way of acquiring a nuanced view on a subject, outside of a small selection of alternative media.
I'm regularly seeing dead Twitter embeds on blogs that rely heavily on Twitter. The solution for non-video content is simple enough. Video is the problem.
Of course, it's not always that Twitter is deleting the content, but, in many cases, the original uploader will also delete it. Both Twitter and its users are quite fickle.
(Likewise, the same can be said for easily acquired URLs online, when it's really better to screenshot everything.)
Twitter and other social media are also purging more content on a regular basis. Who knows what will be available amongst the small sliver of worthwhile information in a few months? How much of the internet might be cleansed of what elites don't want you to see?
Books are banned from Amazon, other large book chains follow suit, and smaller book stores are being driven out of business. A lot of books may be unavailable for a while, until they're picked up by smaller publishers, like Antelope Hill, Arktos, or Imperium. Old rap albums censored, old films and TV episodes are removed from streaming sites. Will the valuable content found on sites like Archive.org remain? Only time will tell.
In the meantime, any useful content needs to be made as secure as it can be on the internet—i.e., downloading youtube videos or images from the internet and hosting them yourself rather than linking—though a link should be provided for as long as it will last. If you find a novel piece of information, it should be stored on an external hard drive. Google was amazing for finding information, but now with delisting and their curation of internet content, it's largely propaganda. Bing and DuckDuckGo are a bit better when it comes to finding less biased search results, but it's only a matter of time before they go the way of Google.
