If it's here, it amuses me, or I think I might use it one day. This Tumblr is just my internet garage, full of crap I'm hoarding. Feel free to browse, but don't expect original content.
If something within is your original creation and you'd like credit, let me know. Unless I took it from your site, it's often damn impossible to find the creator. No harm intended.
I reblog if it's easy. If your theme is horrible and I can't find the reblog option, or if I only want one picture from a massive post, I won't. Finding something before others is not a way to measure your self-worth. If you aren't the creator, you deserve no credit, and shall receive none.
