Oh, compared to blogger, LJ wins for interaction. But for ease of use in terms of the person running the blog, Blogger can be much easier to figure things out. I completely redesigned my layout at blogger with very few issues; I'm still using a default LJ with my own CSS, as I simply can't get my head around layers &c.

LJ is very (very) good for interaction once you know what you're doing, but the learning curve is steep, and most rarely if ever look at the FAQ (you freak ;-) ). Even if they do, it's frequently outdated, unclear or simply not telling people what they want to know, the 'getting started' bits simply aren't there, although the new account/first post thing is an improvement.

Blogger=very pulpit like, and I've now dumped it for most and will bump it for all my sites soon. Wordpress is simply much better for what blogger does, and can be as good for what LJ does, nearly. The bits missing we'll get to eventually.
