I digress... back to the new Blogger - despite the inconvenience caused during the switch, I'm quite happy with it. The main improvement is that it seems much faster than before, which is great news. The interface is familiar but slicker, with a bit more functionality like the ability to see comments associated with blogs. The 'label' system is also pretty cool for organizing posts. Best of all, because of the more solid Google accounts system (which is more adept at warding off spam accounts), the annoying CAPTCHA crap is no longer forced upon me when I post comments.
All in all, there's a slight annoyance involved in using a different browser, but the benefits outweigh the negatives. For people who don't use Google accounts normally, the benefits are such that making the choice to switch should be a no-brainer.
