@nzlemming @mike @Luke I've been thinking that a co-op gif chooser might be a good idea. We want to enable people to create and share gifs but, they're terribly resource-expensive without the efficiencies of a shared third-party pool.
But I also feel that the absence of a gif reaction is a good nudge.
@Luke It's function of file size. So photos are bad but animated gifs are worse (and video worse still).
The most popular reaction GIF - "And I Oop" - is 4.657MB. That works out to 214.7 copies per GB, or ~$0.02 (USD) each on a cut-rate cloud storage service.
Your header JPG is 147kb, which works out to $0.0007.
@Luke On self-hosted single-instances, it may not matter, but the cost scales with users.
For mastodon,social today - 154k users - all the header pics cost ~$90 but one copy of "And I Oop" each would be ~$2800.
So, yeah, if we're going to have memes and reaction GIFs, we're going to want to sort out the shared storage server soon.
