For several years, I've used a custom web app, which I wrote, to capture timeline info. It generally has worked pretty well, except in cases where the bride wanted something non-standard. This week, I'm switching over to Google Docs and am liking it so far. Used it to create the timeline for my Friday event (phone consult) and then created another for a June bride. I thought about changing over to one of the paid services but, besides me being cheap, we also need the ability to share misc docs, photography shot lists, etc. I think it makes more sense to make a folder on Google for each event, copy in the standard templates, then share. One thing that I really like is that google tracks all revisions, so there's an exceptional paper trail. What do you guys use?
