respect
I sent a letter to an artist I admire and told him how great he is in a slightly creative way (ditched ‘you fucking rock’ and stuff like this). It felt nice. What are the odds that he replies? It does not really matter, hope he got it though.
In order to achieve world domination and eternal glory you have to show people some respect and appreciation.
Meanwhile in reality: a really nice feat in Tumblr. You can separate keywords with typing comma. Cute.
