The amount of nice #photography posted without #alttext is growing fast.
It's shame but we may have reached the point where it's pointless to resist verbally.
There may be alternative methods of #resistance such as reposting the photos with #alt text but I suspect that would cause two problems.
1 we'd have to expend a lot of effort in that endeavour.
2 the original posters might not like the one step removed promotion - where they can't see who's reposted their work.
It's puzzler!
