Here's the excerpt! Does it work? Let's see how this performs, up to and including handling of headings:

h1: Drupal is

h2: the best

h3: CMS...

And so on. (Boy, it's annoying that I have select the whole phrase before I can apply the heading...)

Now, this also appears to offer excerpts, but we'll see how well that works...

Edit: Meh. I see have to use Full HTML formatting, in order for the headings to work. Fine. But the excerpt? As expected, it's no go, as I'm using Nodeteaser instead of the default excerpt method; the break tag appears in my MarsEdit editing window, but Drupal and Nodeteaser ignore it. The excerpt text ("Here's the excerpt! Does it work?") just gets slapped onto the front of my post. There's no way to enter an alternate excerpt that Nodeteaser recognizes as a teaser.

See my lamentation about teasers: http://www.drupalace.com/blog_entry_drupal_mystery_1_teasers_2007_06_25 . We sure could use a blogging client made expressly for Drupallers, with support for a zillion ever-changing modules and all!
