Thank you and I agree that word definitely has negative implications.
Tumblr is pretty easy once you get the hang of it. Make an account, then follow who you like. There is a little heart to like posts. To reblog hit the reblog button and you can choose to add tags so you can search your posts later. To post just hit the post button, write/add pics and tag so it shows up in the main tumblr tags otherwise no one will find your posts and it will only be contained to your blog. Tagging is where most people mess up: see the little # symbol? That's the tagging button. Click that.(this is on mobile, desktop is same but different layout)
You type in your tags, for Doom posts I write: victor von doom the either hit the enter or the comma , symbol which acts as the end and completes the tag. Then I write doctor doom and do the same thing.

The A is text post. The chain is if you want to link something from the internet. Gif is gif. Photo is for adding pic (only up to 10 on mobile but you can add more on desktop) head phones is for audio. Here's a link for more help:https://crello.com/blog/the-beginners-guide-to-tumblr/
Also I post Doom very sporadically since I post whatever I'm reading/thinking at the moment on my personal blog, my Namor sideblog is better for Namor content. But if you want excellent Doom content you should follow Doom Archives! I love their blog and they know so much about Doctor Doom.
