I wrote a very small Windows application which somewhat replicates w.bloggar but has a few added (and subtracted) functionalities. It allows (in its crudest form for now) posting to multiple blogs simultaneously, comment, ping and category controls, support for --more-- and excerpt functionalities etc.
Please check it out at http://dinki.mine.nu/word/index.php?p=58&more=1&c=1
If there is any recognizeable interest in this application, I will continue development, otherwise it is going to remain a personal tool. Admins, if this is inappropriate, please remove.
Thanks and Peace.
