I've made it to the homepage before, but I don't get to choose what gets picked. it's all up to the mods and I don't know how they decide what gets picked. I'm not sure if it depends on who many votes or how many people favorite it or what. it's always random.
Nice, making friends online can be tricky. I think the best way is just to message people, you have common interests with, and keep talking if it works out. I've met tons of great people online in that way. I'm happy to say I have penpals all over the world. I enjoy learning about other cultures and beliefs. I'm not on youtube, but I am on DeviantArt, my work isn't pony exclusive like my memebase account, but most of it is short stories and poetry rather than visual art
