I actually joined tumblr about a year ago a little after I turned 13 (I registered as a parent for the respect I get- nobody pays attention to the Teens and Kids reviews) to follow a certain Doctor Who blog. Since then, I've followed several hundred blogs. Tumblr actually helped me realize that I was bisexual, and how feminism is about equality, not oppression of men. Tumblr everyday gives me random tidbits of information concerning facts about science, math, tips on how to draw, college tips, masterposts on how to deal with homework, among others. Yes, you can run into porn, but that's the same with everything else. If you follow porn blogs, you get porn on your dash. You can set a filter so you block out porn and inappropriate content. I've been on tumblr for nearly a year and I've followed 600 people and I've never seen any porn, the most being artistic nudes, which I'm fine with, as I respect and enjoy art. It's also great because you can meet friends online. I've had depression for several months now, and my online friends on tumblr have helped me through it and I'm much better now. Most of the people are incredibly friendly and very open to ideas and new people. There are many good fandom blogs that are fun to look at and also humor blogs that reblog text posts- oh, and tumblr has a multimedia blogging system so you can blog GIF files, pictures, videos, audio and text! You can reblog anything and like anything. So you don't stay on too long, tumblr also has a set daily post limit which includes reblogs and a daily like limit. People on tumblr are also very relatable, because they like similar things and sometimes are going through the same things as you are. For me, joining tumblr was one of the best decisions I've ever made. Yes, there is swearing, but we've all heard it all before. Yes, there is consumerism- but only if you look for it. If you like a certain brand, you're going to follow that brand, same as with any other social media. If you follow a violent blog, you will get violent images. However, if a website like 4chan hacks, you will get a notice on your dash (if someone you're following reblogs it) saying which tags have triggering images and which tags to avoid, to keep everyone safe. Tumblr is a wonderful community filled with wonderful people, if you know where to look.
