Windows Live Writer and Blogger returned the following error: Notfound: not found

Ah Windows Live Writer--you've been there all along and now you're not working because Google ended support for ClientLogin OAuth 1 (3LO), AuthSub, and OpenID2. Great for Google, no doubt, not so great for the thousands of users still clinging to WLW.

Microsoft insiders (Scott Hanselman) are talking about open sourcing Windows Live Writer, which would be great as the application hasn't seen any major updates since the 2012 product release. Hanselman has also suggested a fix may be a while off--in the hands of the open source community. 

Apparently Google is also considering a fix at their end, which would be great to keep us bloggers running in the meantime: https://plus.google.com/u/0/+RickDoyle/posts/GUPJcu5sZHo

Update: a few workarounds have popped up around the web:

1. View source in WLW and copy/paste into Blogger (web). See http://mybeerbuzz.blogspot.com.au/2015/05/blogger-windows-live-writer-blogger.html
2. Configure posting by email. See http://www.hackinguniversity.in/2015/05/live-writer-not-found-error.html

Update 2 (3 June 2015): seems to be working again as expected :-)
