Fritinancy recommends this website: Samosapedia. It is a guide to South Asian lingo. 2,500 words have been added to it since it launched in June. They also have a "daily dose of chutney" (a word a day) that you can sign up for.
Language Johnson, which is a blog about Indian English, also recommends it, and this blog itself may be an interesting read.
Johnson is a general language blog, not one specifically about Indian English - just that article. The blog is run by The Economist. I've been subscribed to it for some time, pretty well since it started a year or so back.

Ah, thanks arnie. I hadn't heard of it before.
