I've stumbled upon Grazr, which I really like (for now). It's a different way of viewing your blogroll in opml 1.1 format. It's snappy, cool and very web 2.0 like.
However, it's quite an ordeal to use something like opmlmanager or blogrolling to manager your opml file, while, let's face it.. you already have setup in your precious rss reader. I use the excellent RssBandit and I obviously just want to export my feeds (including categories) as opml and read it into Grazr. Well, it seems that the Grazr api is very strict about opml and only accepts version 1.1. RssBandit exports to a totally different schema (1.0) and conversion is needed. I found a converter by Matthew Hazlett for the native rssbandit format to opml 1.0. I adjusted it to use the opml 1.0 exports of rssbandit and spew out valid opml 1.1 files. The result can be seen on the right side of my site. I will categorize my feeds soon, for your viewing pleasure. I hope you like it.
There was one weird caveat though: when converted by xmlWriter with an encoding of utf-8, there would be a byte order mark that Grazr does not except. I've had to choose ascii encoding to get around this. If there are people that are going to use the converter and feel a strong need for utf, I will do an update and use the bytewriter to delete those pesky 3 bytes. My guess though that Grazr will lighten up and start accepting pretty soon.
