Feedburner also lets you offer email digest subscriptions. Login and click on "Publicize", and you'll see that option. Just activate it, and they give you the HTML to create a form on your webpage that lets people sign up for a daily email digest of posts.
Oh, and once you have a decent amount of subscribers to the RSS, you may want to publish the chicklet version, which shows the number of subscribed people. Code is available under Publicize, I believe.
That's great! 1,300 is nothing to sneeze at, so soon out of the box.
Generally speaking, if someone is subscribed to your RSS feed, they wouldn't friend the feed on LJ - it would just clutter their friends page with content they're already getting elsewhere.
And certainly not that you don't have plenty of other awesome resources, but if you ever have web/rss/whatever questions, feel free to drop me a line. Been doing this for about 13 years now, and I'm happy to lend any insight if needed.
I do both, myself. Same with Dinosaur Comics and Irregular Webcomics. I enjoy the discussion on the LJ feed, especially on those. Places like Punch 'n Pie or Something Positive, not as much. Not sure why. (Actually, I know exactly why, but this isn't the place to gripe.)
That's why I said "generally speaking" :) I personally don't typically subscribe to LJ group RSS feeds if I'm already watching the feed in a feed reader. My friends page is already so flooded, and I barely get a chance to look at it - AND I've got that RSS in my reader.
Excellent point tho - I expect many people feel as you do and enjoy the extra discussion. :)
Okay, sure. What do you need besides the existing feed?
(Note: If you need a different version of the image, I can't help you. Besides, phones are catching up -- you'll be able to consume this feed and read it no trouble on any mobile device you care to use in a couple of years.)
Mostly narrower content. It would be sweet if your site could auto-detect mobile browsers and switch to a narrow format page without all the framework/columns that are so popular with current page styles.
Of course, lack of flash/java is useful to as those are quite iffy on the mobile folks.
