It might be longer than a year, but regardless, the sooner you start using RSS and blogs to your benefit, the more rewards you reap.
And is a bit misleading. RSS is not email; just because you can have it delivered to you in the form of email using and other RSS readers doesn't mean RSS is email. Unlike email, most items in an RSS fed are on the Internet with a permanent URL so if you don't read a particular item in your RSS reader or delete it from your RSS reader, you can find it again.
From Micro Persuasion: NYT Column a Watershed Moment for RSS:
...RSS finally broke into the Times Business section today, which is a big deal.
In the Sunday Business section this week, columnist James Fallows wrote about how blogs and RSS are enhancing society's collective knowledge.
Blogs have also become easier to navigate, through the system known to techies as R.S.S. I've sat through debates about what those letters originally stood for; what they mean is that you can have new entries from chosen blogs automatically delivered by e-mail soon after they appear. Some people would rather skip R.S.S. and just cruise through favorite blogs periodically. Others like the convenience of a regular R.S.S. feed: it's like home delivery of mail instead of a post office box, but on a much faster cycle. My current favorite among R.S.S. programs has an ugly-even-for-software name: intraVnews. It presents blog entries, sorted by topic, in my Outlook mailbox, and it is free.
A year from now RSS will become part of the lexicon of every tech-savvy business person.
