There are many tools that deliver RSS feed content in an email format, this is RSS to email.
What about the other way around, email to RSS.
You can subscribe to email alerts with a special email address (such as Bloglines offers) and read that email content in RSS format…others are dodgeit, email2rss, pop2rss, egorrss, FutureMail, mailbucket…and many more.
What about this at the tag level, you could set a rule so certain emails bypass your inbox and receive into a tag, this way you can subscribe to new mail by tag and not your whole inbox, as you may be only interested in receiving only select email from your Gmail RSS feed…or even extend this to a search feed…RSSMail comes close to this…also see AfterMail.
What about a feed notification, not for your inbox (as you receive the email), but a feed for a tag (after you have read the email and then file your email), if you don’t tag it and just archive, this will mean you have decided to not share that email.
So each tag can have a feed, if you want to file something in a tag but not want it re-syndicated, then just turn off the feed, tag it, then turn on the feed again…is this possible?
Anyway, this is a way to automatically re-syndicate or publish emails that you are OK to share.
I have posted about RSS to IM, what about IM to RSS, you could file an IM conversation in a tag that has a feed, this again is re-syndicating or publishing IM conversations…an RSS feed for your whole IM account wouldn’t be effective as you are taking part in it (it’s synchronous, you don’t need notification, it’s happenining in real time), although others may be interested in subscribing to the feed of an IM conversation in real-time (well as close to real time RSS can get)
These are just some thoughts I didn’t want to slip away, I can’t really see a great use for them, but others might see the value, or they may trigger other ideas…that’s what blogging is all about!
