Well, the benefits of the Live Writer SDK are already coming true for me. One of my bug-bears with BlogJet was to copy/paste in code samples was pretty tricky. I ended up evolving a manual process of visiting the excellent CodeHTMLer site to convert into HTML and then pasting the source into BlogJet source view (when pasting Java code I just to tell that CodeHTMLer it was C# and it usually looks great.
I was over at the CodePlex site this morning and noticed that Alexander Concha Abarca has posted a Syntax Highlighting Plug-in for LiveWriter.
Seems to work ok so far, the actual plug-in is very simple as it re-uses a code high-lighting engine from Wilco Bauwer which supports many languages including all the ones I may want to talk about such as C#, Java, XML, Perl, Ruby, Python, PHP, SQL, Visual Basic, ASP.NET and even Fortran (if I wanted to post my highly fascinating university projects).
Just in case you are interested and prefer CodeHtmler, there is a LiveWriter plugin for it http://puzzleware.net/download.aspx?file=/codehtmler/codehtmler.livewriterplugin.zip.
