Apart from that, some payment methods (like crypto) allow transmitting arbitrary amounts. At least, paying for years in advance works without issue. You could pay a few cents and try it out, but be mindful of fees.
In the specific case of Mastodon, an instance pretty much only receives a post via federation if one of its users either follows the creator of that post, or is mentioned in it.
Discoverability suffers, because this also applies to replies to a post even if you follow its poster. You might see them, or you might not. You look at the post history of one of the users in a thread and it comes up empty.
This is not much of a problem if you’re in one of the, say, top five instances, but beyond that, many functions become increasingly unreliable. Instead of one big microblogging ocean, it feels more like an assortment of a few lakes and myriad puddles with only tenuous interconnection.
Personally, I’ve kinda given up on finding (or creating) my One True Instance and am resorting to having profiles on all of the biggest instances. This also has the advantage that arbitrary defederation decisions affect me to a much lesser extent.
You know, anyone making negative comments… The bees go get 'em.
Almost all extensions will weaken your security posture. In fact off the top of my head there are basically only two kinds of extensions that could improve it:
Anything else is questionable at best. Maybe you could create browser profiles where you install extensions somewhat more liberally, with decreased expectation of safety.
According to my mom, the calcium off her teeth.
“My dentition was so great, but then you came.”
I’d argue this counts as dog-sitting. The dog is around people in every panel, and actual sitting (i.e. doing nothing else) isn’t required.
IIUC the end goal, for any fusion reactor, is to heat up water and drive a steam turbine.
Imagine you could drive a steam turbine at zero cost. What happens if just keeping that turbine running costs more in upkeep than e.g. solar panels do overall?
Is there really much of an economic case for infinite energy on demand (and that is if fusion can be made to work in not just the base load case) if we have infinite energy at home already?
