Please avoid plain text protocols!

I'll give him one out of three. They are human readable. The are clearly not fast to parse - binary protocols are obviously faster. The biggest problem is "simple to implement".

That's just nonsense. Using text introduces so many ambiguities and tricky edge cases around quoting, whitespace, case, line endings, character encodings, escaping, etc. etc. etc. Soooo much more complicated than a simple binary system (e.g. Protobuf).

There was a link here only recently about how Go might introduce security issues by lowercasing HTTP headers. Would a binary protocol have had that issue? I seriously doubt it.

Don't use plain text protocols!!
