mdmrn, 
Looks like Tumblr is having issues and Fedi is getting another wave of new folks.
Welcome to the Fediverse, new folks!
A couple tips:
Boost freely
Try to put up for yourself an introduction post with the hashtag #introduction or #introductions or both listing stuff you're interested in
Use hashtags freely, they help folks find you and what you're posting!
Use Alt-Text in your pictures. It helps a lot!
