This blog is relatively new (fewer than 30 posts! I probably post that much in a week), and yet Victorine Lieske offers some really solid advice about marketing and soliciting reviews (with more good advice found in the comments).
At first, I didn't think this blog would be very useful, because the author tends to free associate, but the entries on self-publishing are really good. Like Joe Konrath, Robin O'Neille/Barbara Morgenroth (I think the latter is her pen name, but I'm not sure. ETA: It turns out that the first name is definitely a pen name. The second name may be a pen name as well, but I'm not sure) is a refugee from traditional publishing and has great perspective on the merits of self-publishing, as well as a realistic attitude toward books, audiences, and publishing in general, which I always appreciate. She also is VERY adept with design and does her own book covers as well as those for other people. (ETA: Having read further through this blog, I shall warn you that she really, really does not like transgendered people. I don't know what they ever did to her, but God, she hates them.)
My quandary is that I just don't feel like it's appropriate for me to be Tweeting away about self-publishing given what's going on in Japan. And yet it seems like everyone I follow on Twitter is just continuing business as usual. But of course for most of them it is a business--they'll still have to pay the rent at the end of the month whether the death toll is 1,000 people or 10,000 people. I can afford to be all sensitive, I suppose. I'm nearly out of Tweet-type blog entries anyway, so I think I'll take a break and get back into it later--it just feels really crass and solipsistic to be out self-promoting under the circumstances.
