If you know that what you compress is alphabetised text, and space is more important to you than time, then please use lzips over gzips. For a parallel version:
Is this gunzip-compatible? If not, then as long as gzip remains the only viable/compatible compression mode for HTTP I think advances in gzip compression is still valuable.
I don't think the comment you replied to suggested that gzip is not valuable, only that there's specialized compression available for a special case (alphabetized data).
