Hi,
What I cannot find those enticing words advertising the product why anyone would want to use Octopress instead of plain Jekyll.
There is a list of features, but without prior experience with Jekyll they don't seem absolutely necessary (or even unavailable in Jekyll) now.
I'm talking about developer blog.
Could you summarize important benefits for you?
I hope this may become source of why-s for others too (and may be partially included to the top section in the docs).
