To get approved for a book, some publishing companies required that you have, say, 800 followers and 20,000 twitter followers. Fortunately (whew) many companies have little or no guidelines.
Here are the pros and cons to NetGelley:
1. FREE BOOKS. You can't top that.
2. More occasions to blog. I love having an excuse to do that.
3. While you are obligated to write a review, you're not obligated to finish the book. Recently I got approved for an e-book that didn't turn out to be something I was interested in. I simply deleted the book from my kindle and mentioned in my review why I didn't finish it but that there were still some good parts.
1. The archive date. I didn't realize one of my book reviews was four days late.... Fortunately, the book wasn't un-downloaded from my computer and I'll still be able to add my review. The book has just been taken down from the website.
2. A book you request might end up not being something you want to read.
3. Sometimes the only format available is to download it to your computer, which is pretty inconvenient for me. I can't carry a laptop around with me everywhere (hence the book that missed the archive date).
4. You might not get approved for the book you want.
All in all, however, nothing trumps a free book, except for maybe a Dairy Queen Arctic Rush with ice cream up the side. Thank goodness for NetGalley.
