So today I logged in to TypePad and saw a new feature that doesn't seem to be publicized yet: "Feature This Post". It gives you the ability to promote a post to the top of your weblog regardless of publish date.
This is a really useful feature for lots of my clients who want to use TypePad as a website building tool as well as a day-by-day publishing tool. A good example is the St. Benedict Elementary School-- when I made their site a year ago, I had to create a second weblog to handle the Principal's weekly newsletter.
With this new feature, we can do sites like this in one weblog. Thanks, TypePad-- you're on the right track!
