IBM's enterprising broker-brainiac has moved from Blogger to WordPress.
I looked into this last weekend - and have even gone as far as opening an account. However, I haven't had time to perform the migration.... Andy makes it sounds relatively straightforward.
However, his "pros and cons" scorecard suggests that I can't add Google AdSense to the blog. My earnings from AdSense are currently somewhat low (zero cents, to be precise) but I harbour the hope that, one day, an exponential (indeed, infinite) increase in my AdSense-related earnings will materialise. It looks like I'm going to have to make a difficult trade-off.
