Personally, I love Windows Live Writer. Being able to write blog entries on the train is great, editing in your web logs styles is cool and it's also a neat way of capturing notes during meetings.
Over the last few months there have been a number of occassions where the blogger beta changes have broken the live writer betas. The Live Writer team have done a great job in responding quickly when blogger changes break something else. They've also fixed an annoyance in using the keyboard to select sections of text (selecting text with shift+left would work, but moving back with shift+right wouldn't).
Yet another update for live writer is out which fixes the problems I was having previously. It's also a little different in that it has a 1.0 version number (which is strange for a beta) and the install takes you to an install-success web page.
Other than that - let's hope there's not many more breaking changes. Blogger beta is feature complete so that should help things settle down somewhat - well, here's hoping anyway.
For now - Back to train blogging again!! Yay!
