This article pretty much says it all, on why it’s generally a mistake to DRM your ebooks. Some DRM supporters liken it to locking the door on your house – but that’s a false comparison. It’s more like locking a door on your storage locker in a foreign third-world country that has one thing you created that can’t actually be taken away, just copied. In other words, the only people you will inconvenience are the law-abiding citizens who bought your books and supply you with your sales. Why would you want to do that?

This one I thought was interesting, especially the last paragraph. I came up with its conclusion long before I read it, just based on the early part of the article – to wit, as an author, buying my book and not reading it is almost as good as buying it and reading it. If they buy it and it sits on their Kindle, the only downside for me is that they may not go on to buy more of my books, especially if it’s a series.

This one has a lot of good info and links on hot topics of today like the Hydra debacle and why indies are better than tradpubs – or at least our model is better.

Here’s a great post about piracy and why we should not worry too much about it. Better to expend that mental energy writing more books. The BLUF is that piracy is a confusing and sometimes didgitally dangerous way to get free stuff – rather like going into a really bad neighborhood to the thrift store in hopes of getting a deal – and most people tend to go where the combination of convenience and price is acceptable to them (think wal-mart or target).

Here’s a so-so but still interesting article one on where we might all be going soon – and by all, I mean indie authors who are serious, productive, skilled and at least somewhat talented, and oh yeah, determined.
For all of the dilettantes, nevermind.
Hybrids may be where tradpubs and indies meet in the middle, with the best of both worlds – profitable product for the TPs, and creative and economic freedom for the author. Somewhat like how free agency changed some sports over the past couple of decades by forcing employment models to change. The writer uses rather the automotive hybrid model, but I think my metaphor is better. Another metaphor might be telework freeing the office drone from a location and his or her commute, while still working for the big corporation.

There’s actually more on the subject tucked into this one:
David VanDyke's Author Blog 
Interesting list. I’d definitely rather people actually read my books than just left them sitting on their e-reader though – that way, as well as the possible sequel purchases that you mention, you’ve got some chance of a review and/or word of mouth recommendations, and I think they tend to be a big part of success.
I wish it was possible to tell when purchased books have been read and how far through them readers have got. If as a writer you knew that a large proportion of readers tended to abandon the book after a certain scene or read a section in the middle really slowly (so could assume they found that bit either dull or confusing) you could do some really productive post-publication editing. I’m pretty sure I once read that Amazon does have this data but there’d obviously be major privacy issues with the sharing it.
