Steven Den Beste has some interesting comments on Blogspot and Blogger. He does a good job summarizing some of the problems, but since he does not use these programs himself a few points should be clarified. I use Blogger and it is not nearly as bad as presented. It should not be lumped together with Blogspot. Blogspot is horrible and people are fleeing it in droves. But if one uses Blogger with their own site, as I do, there are no real problems. Even if Blogger should lose all of my archives, I have backup on my site – which I also burn to CD when I do my regular backups. When used properly, Blogger is no more risky than any other program.
I can confirm the work-around (manually republishing your archives) for the permalinks. When you do your first post of the day, the permalink works fine. But future posts (on the same day) will not have a valid permalink unless you manually update your archives or you wait a day when Blogger automatically updates the archives. I’ve tried MT and bumped into problems with some of my readers who prefer low screen resolutions (not just MT’s fault, I use frames and most people no longer do this). I am considering switching to Nucleus after discussions with Kevin Whited, but will hold off until I see what Google does with Blogger and how Blogger's newest release works.
