Every Fediverse content looks a little different, depending on which access software or app you use to view it. It seems that there are also Lemmy apps that display hashtags a little too exaggerated, while in others and in the web-gui it is ok. (in an earlier version of the guide it also said that you shouldn’t use hashtags/tags esp. in the headline because it didn’t work properly back then).
But maybe I should include a note in the instructions that hashtags should be used sparingly or placed at the end?
I’m not a big fan of Mastodon either (started with it, but now prefer Friendica and Lemmy), for me personally it’s not a good fit. But hashtags on Mastodon are at least a way to follow not just individual users but also topics (and this only works if they are hashtagged). With Friendica, Sharkey and others, you can define your own individual channels / antennas for certain topics, so hashtags and individual accounts are not so important. And for Lemmy, they’re not important at all. But as a Lemmy user, I can still put up with it when I see a hashtag (that gives others an advantage). What’s so bad about seeing it?
