Okay so I just went to create a multiple-choice poll and hot damn if that's not a totally undiscoverable interface, I was flummoxed for much longer than I should have been.
(For those who haven't encountered this, you have just guess that clicking on the radio buttons next to the poll will change them to checkboxes 
)
I'm grimly unsurprised that Eugene pooh-poohed this exact complaint already (because multiple-choice polls are "not a priority" and it would make the interface "too complex", and it's fine as "an easter egg"): https://github.com/mastodon/mastodon/issues/10873
I have a bone to pick with a definition of "complex" that results in hiding basic features behind UX mechanisms that are impenetrable to the average user, creating a two-tiered experience where nerds like me who are steeped in How Computers Work get to have extra "easter egg" features like...allowing people to choose more than one poll option 🙄
And in this instance it's especially silly, because the first two other interfaces I checked (Pinafore and Tusky) have entirely reasonable interfaces for this, both have dedicated and labelled "multiple choice" options, and neither have the radio buttons (because they're totally unnecessary for creating a poll!)
I don't have screenshots, but from looking at the source of glitch-soc it seems like they also have a reasonable interface for this. Looks like Hometown uses the stock Mastodon interface, but I just filed an issue to look into improving on that.
In the spirit of not complaining without trying to fix it, I also intend to comment on the Mastodon issue, but right now my brain is tired of digging into this so that will have to wait for a bit.
@Claire @cincodenada Maybe taking inspiration from Pinafore or Tusky’s wording would help with glitch-soc interface
@cincodenada glitch-soc is kinda wonkey because the option's text is too long in most layouts, but yeah
for the record, i implemented the “easter egg” thing after Gargron refused to make it a proper dedicated control to “not clutter the interface”
