On Paleojudaica, Jim Davila grumbles about the upgrade to Blogger, which I use too. I've actually quite enjoyed the new format myself, but perhaps partly because I don't have the paragraph-break problem Jim mentions, perhaps because I don't work with a Mac. On one of Jim's points, the date and time one, you can make an adjustment manually by clicking "More Post Options . . ." at the bottom of any given entry and then adjusting the time. I find this useful because I often write half a post, get disturbed and can't get back to it for some time, sometimes after I've published others in the mean time (e.g. now I have one pending on the Open Scholarship issue). In fact I tend to think of there being broadly two types of blog entry, the one notebook style entry which goes up quickly in five minutes or so and the other the mini-essay post, which takes a little longer and has more of one's own prose in it.
A couple of things I like about the new blogger: the archiving is greatly improved by separating off posts into single pages with single URLs, which means that when one searches for a given post you can go straight to it rather than getting to the page on which it appears. I've also noticed that other users of Blogger are now using its Comments function. I still have comments from Haloscan which date back to the time before Blogger provided their Comments system. Ideally I'd like to move to that too, but it will mean losing all the Haloscan comments.
