On Tags (including Hash-Tags) in ActivityPub.

I think new developers coming to ActivityPub want to write something like:

"tag": ["apple", "banana", "cherry"]

It is unfortunate that that isn't valid ActivityPub. But, that it must instead be:

"tag": [
{
"type": "Hashtag",
"name": "#apple"
},
{
"type": "Hashtag",
"name": "#banana"
},
{
"type": "Hashtag",
"name": "#cherry"
}
]

On Tags (including Hash-Tags) in ActivityPub.

A new version of ActivityPub could extend the type of "tag" from:

Object | Link

to:

Object | Link | xsd:string

And that would make the following valid ActivityPub:

"tag": ["apple", "banana", "cherry"]

Of course, it would have to be specified how to interpret this. (Ex: as "type":"Hashtag", or whatever.)
