It occurred to me today that GameFAQ, a fantastic game guide resource, still requires guides to be written in plaintext only. If you haven’t seen a GameFAQ guide, you really should — those guides are well written with more insight than most printed guides.
Their “GameFAQs Help : Composing Your Guide” document is full of gems like these:
Watch your FAQ size – While some people think having the largest FAQ (in terms of size) is better, keep in mind that many people are still using their old 56K modems to browse GameFAQs, and they’ll be upset when they wait several minutes to download a 500KB file with only 50KB of actual gameplay content. Having small amounts of ASCII art and dividers is fine, but when used to excess, these can increase the signal-to-noise ratio of your guide beyond what will be accepted.
