Open Live Writer is an open source tool - a fork of Microsoft Live Writer - which allows you to create blog posts, add photos, videos, maps or more, and publish them to your website.
The program supports various blog services, including WordPress, Blogger, TypePad, Moveable Type, DasBlog and more.
Licensing and other issues means the development team has dropped some of the old Live Writer features. Spell Check has gone for the moment, the Blog This API has been ditched forever and the OneDrive "Albums" feature has also disappeared.
The good news is that the team is "actively working on supporting plugins", and as soon as that happens we should see third-party developers filling any functionality gaps.
Please note, if you're currently using Microsoft Live Writer with a Blogger account, it will stop working soon when Blogger switches to the OAuth 2 authentication scheme. You'll need to move to Open Live Writer to continue using the program.
Microsoft Live Writer was a great package, and it's good to see an open source team update, maintain and expand it.
