Gregory's Server@Voline Regarding the search function: I believe this is not entirely true and depends on the instance your on. Mine for example runs Elasticsearch which offers fulltext search. And I can actually find toots based on single words without hashtags.
That's Mastodon 3.5.3
@mrgeneration
“While some Mastodon instances do allow full-text search, you can only search your own toots on those instances. This makes it easier to find something that you posted a while ago without exposing you to harassment.”
