Little endian is genius. Not only because of size casts being "free" (because LE is compatible among "word" sizes -lower bits are at a known location-, while with BE you need to know the word size in order to locate the lower bits of the word), but also because of efficient bit I/O (using CPU registers as accumulators, and flushing with a word-size store), so variable size data can be encoded efficiently.
