Do you have any advice for your followers?
I'm not sure. (Also if this seems too flippant, it's because a lot of what I think makes my blog annoying is what I like about it, so the "I enjoy annoying people" quality tends to outweigh the "I'm annoying people" quality when I'm talking about my own tumblr.)
If you don't have much writing experience and a lot of your blog is about tumblr and tumblr-related stuff, this may be less relevant to you than I think it is, but I hope these points are useful:
Tumblr is a really weird site. A lot of the stuff that makes tumblr annoying is just a result of having to learn that weirdness. To some extent, it has to be weird in order for it to be appealing – it's not like other social media sites where you only have to learn what works there. For instance, a lot of tumblr culture is "being in the know about current events is important and interesting." Being in the know about current events is important and interesting, and yet most tumblr users are too young to fully understand the news, so there is this weird tension.
Some of tumblr's weirdness is actually good in moderation – the "tumblr" format, the weirdness of fandom and fan culture, etc. If you like that stuff, fine. But don't make it the whole of the experience, unless you are also very good at keeping track of that stuff and talking about it in ways that don't turn off people who don't like that stuff.
The thing about tumblr that gets me the most is its lack of standards or formal structure or anything at all like that. I don't think I will ever be good at writing a book – not because I am bad at writing, but just because the concept of writing a book feels weird and unnatural to me. On tumblr, I can post my opinions on how tumblr is good or bad, people like my opinions, I get tons of notes, I can find the posts with the most notes and enjoy reading them (which is very pleasant) … and then I can leave. And tumblr will go back to being a thing where I don't read people's posts and don't enjoy anything about it. And that's okay! It's a nice life! This can make some of the social stuff hard to do – for instance, some people find reading text and "reading comprehension" very hard, and are often put off from interacting with a lot of tumblr posts. This can be a lot easier with things like fanfiction, which has very obvious standards (e.g. writing is "good" if it follows the "rules" and "bad" if it doesn't), and which people often want to share with others in different format.
Tumblr has many good people who enjoy interacting with tumblr stuff but don't necessarily like the weirdness, and many others who like the weirdness but hate the format. I know of some people who I've followed for a while and thought were really nice who got really annoyed by what they saw as some people's obsessive focus on things like "tumblr culture" (I've definitely been guilty of this myself). I want to avoid people who hurt you on purpose, and if you want to avoid those people, don't spend more time on tumblr. The people who get annoyed at the format are often making a good faith effort to avoid "hurt" people, and trying to find ways to make it work, but – as I say above – it's really hard for them.
Don't make assumptions about how much people like certain things or don't like certain things. Some people will like you, some people will not like you, some people will like some things and not like other things, other people will like some things but not like other things. You can't figure out in advance if someone will like you, because that's part of the human experience.
