@Dr. Mike: just to make this more complicated, I don't entirely agree to the fact that a value of zero would make the widget redundant.
The widget is great: it makes it easy to highlight the 'existence' of your feed (not all templates make it easy to find it) without having to create a bookmark with an icon that you first have to find somewhere, then upload, then link to.
But why zero then?
1. The most recent posts will already BE on the page right next to it. Why duplicate the titles in the sidebar and lose space?
2. When people subscribe, the feed will be loaded into the feed reader anyway. Why announce the titles of the posts they will be getting in a few seconds (and have probably already read, why else subscribe)?
That said, I'm perfectly happy with things as they are now, thank you ; -) It's just something that struck me as a missing possibility the moment I saw the widget was available.
@evolvingtrends: write significant posts all the time then ;-)
Seriously though, things never being read is of course a risk that you run by blogging anyways. Older posts disappear into the archives and often into oblivion. That is what happens to a lot of things in this fast-paced society. But people who like your blog, will not hesitate to browse these archives - I know I do and many of my readers have surprised me by doing the same.
If you are concerned your good posts might get lost (I have that too at times, so it's not criticism), how about using a text widget linking to your favourites or highlighting your 'best received post of the month' or something? Just an idea, really.
