RSS or Twitter Feed to recent technote published articles - eg NetBackup
This might already be available but haven't seen how to do it.
As a NetBackup Admin I regularly visit the web page Publishing DIGEST for NetBackup Enterprise Server which shows the last 45 days of published technote articles for that product.
The list can be long, but I see no RSS icon for this page, that would be a great resource to make available in my RSS reader.
Also, I did sign up for twitter and see what all the fuss was about, and didn't use it until a colleague notified me that VMware and Novell are using it to publish shorthand notifications of product and more specifically Knowledge base articles.
I have found this a great way of getting straight to the information I want, in a concise manner.
