You see, if I'd made that statement in the public fora that were available back in the days of 2E, it would have taken at least a month for your response to be made public, and it would have to pass through several intermediary steps (write the letter, send it in, have the editors decide to run it in DRAGON or a fanzine). With the rise of the Internet, gamers can now communicate in a much faster and more unregulated fashion, and with a much broader audience. This means that issues can be discussed in a faster and broader way than back in 2E's day, and thus companies can receive feedback on design much faster than they did, which contributes to an accelerated rate of revision. Desktop publishing and faster printing technologies (not to mention the rise of things like web-based errata and, for smaller companies, PDFs and print-on-demand) also means that a new edition is not necessarily as dramatically time-consuming on the production end, although the design end probably hasn't accelerated so much.
