I just read Jon Udell's post on What RSS users want: consistent one-click subscription where he wrote

Saturday's Scripting News asked an important question: What do users want from RSS? The context of the question is the upcoming RSS Winterfest... Over the weekend I received a draft of the RSS Winterfest agenda along with a In an October posting from BloggerCon I present video testimony from several of them who make it painfully clear that the most basic publishing and subscribing tasks aren't yet nearly simple enoughrequest for feedback. Here's mine: focus on users. .

Here's more testimony from the comments attached to Dave's posting:

One message: MAKE IT SIMPLE. I've given up on trying to get RSS. My latest attempt was with Friendster: I pasted in the "coffee cup" and ended up with string of text in my sidebar. I was lost and gave up. I'm fed up with trying to get RSS. I don't want to understand RSS. I'm not interested in learning it. I just want ONE button to press that gives me RSS.... [Ingrid Jones]

Like others, I'd say one-click subscription is a must-have. Not only does this make it easier for users, it makes it easier to sell RSS to web site owners as a replacement/enhancement for email newsletters... [Derek Scruggs]

For average users RSS is just too cumbersome. What is needed to make is simpler to subscribe is something analog to the mailto tag. The user would just click on the XML or RSS icon, the RSS reader would pop up and would ask the user if he wants to add this feed to his subscription list. A simple click on OK would add the feed and the reader would confirm it and quit. The user would be back on the web site right where he was before. [Christoph Jaggi]

Considering that the most popular news aggregators for both the Mac and Windows platforms support the feed "URI" scheme including  SharpReader, RSS Bandit, NewsGator, FeedDemon (in next release), NetNewsWire, Shrook, WinRSS and Vox Lite I wonder how long it'll take the various vendors of blogging tools to wake up and smell the coffee. Hopefully by the end of the year, complaints like those listed above will be a thing of the past.
