I've redesigned the front page (again) so that it displays 40 word excerpts from blog posts, rather than the full text of the post. A similar treatment is given to archive and category pages. The automated excerpting is a new feature of Typepad, and I figured I'd give it a go, knowing that I could always bring back the original with a few clicks.
You can see it at http://vielmetti.typepad.com.
So far so good, I guess. I don't have strong preferences about it; the advantage is that more short posts fit on a page, making it easier to scroll through a lot of them. The disadvantage is that I don't know where the 40 word mark is, and there's no really obvious way to say "always excerpt the lead paragraph", which is what I want.
Fiddling with your blog is the traditional way not to write. If I had to fiddle more, I'd look for a design that worked better on mobile devices like my Android phone; the current design has a weird choice of fonts for blog title that comes out too small, and my CSS-fu is not adequate to the task of debugging and fixing it.
