So you have decided to go for it and start blogging. You want to sign up for the free variety just in case you find out it’s not really your thing. Also, the more documentation available the better. Hello WordPress :D
Here comes the most difficult part. (see post title) You can’t use common phrases cause they’re taken. Same goes for famous quotes, poetry and movie references. Provided, of course, that you at least have a general idea of what the blog is to be about (if not, meditate on this you should) you can start searching for obscure references or start making up words.
Following the first path, and keeping within Tolkien’s Middle-earth, I remembered the song that sits in italics in the right corner. I also found there are three versions of it in LOTR alone, as well as another version in The Hobbit (from which I borrowed the one line):
Roads go ever ever on,
Over rock and under tree,
By caves where never sun has shone,
By streams that never find the sea;
Over snow by winter sown,
And through the merry flowers of June,
Over grass and over stone,
And under mountains in the moon.
Roads go ever ever on
Under cloud and under star,
Yet feet that wandering have gone
Turn at last to home afar.
Eyes that fire and sword have seen
And horror in the halls of stone
Look at last on meadows green
And trees and hills they long have known.
