Thanks to Kevin for pointing out a very stupid mistake on my part with hyblog: having something enclosed in double quotes when it needs to be single quotes.
It's something I fixed in my demo site but forgot to carry through to the repository. It's fixed now.
I also noticed that I forgot to remove the reference to my actual blog from the menu so I corrected that as well.
I've got a rough and ready proof of concept working for the standalone version of /reader. All it does right now is pull items from my RSS feed into an array, write that to a CSV file before pulling reading it all again and displaying the posts on a page.
I just wanted to make sure it could handle it all without messing about too much. I'll need to do some tweaks where posts contain "double quotes" (that's a test) but, in theory, it shouldn't need a lot to get it fully working.
Update: Actually, double quotes were automatically catered for – which I wasn't expecting – so that makes life even easier.
