I got very excited the other day, because I saw that Scrivener are preparing to launch a third version of their writing application. If you haven't used it, the tool is great for organising notes, characters, plot lines, etc. In fact, it is one of the best tools for creating a novel or a non-fiction book, or a screenplay (although it has some competition in that category from Final Draft). I don't use it for short stories, but I do have a couple of other books that I've been working on with Scrivener for at least a few years (hey, I didn't say it stopped you procrastinating).
The funny thing is that I know from experience, that while a new version of the software (any software) will look better, and have a few useful features, it won't actually help me finish either of those two books. Yet, it has stopped me working on them in the short term, because why would I want to use a tool that is old and (about to be) outdated, when I can wait a few months and have the latest shiny toy to use?
If you want to see more about the new version, check out the link: http://www.literatureandlatte.com/blog/?p=1032
P.S. I should say I have no affiliation with them, and I buy the software like everyone else. I just like it!
