This post is part kudos, part comment, part question. So here goes.
Kudos to Ed Kohler from Technology Evangelist for the information in their Google Docs post. It includes a YouTube video on how Google Docs can simplify emails with constantly updated attachments. I’ll include the video here as well.
I fall into the camp of creating documents and by the time it’s proofed, there are four different email attachment updates. It can definitely be confusing to immediately find the finished document or spreadsheet (good thing I’m not a project manager because I would suck at it).
I haven’t used these Google applications but have a question for you all. Do you use Google Docs/Spreadsheets and/or the new Presentations? I know that Google’s spreadsheet option might not fare too well for the Excel geniuses out there (ahem, Telli). And do they integrate with Basecamp?

Hey Paul,
I built my first Presentation on Google earlier tonight. Kinda clunky and you have to have a live web connection or export a .zip file of the presentation for local playing at a series of HTML pages. Some growing pains, but I think the collaboration will make up for it.
Oh, and you can’t do custom themes right now so you have to rely on a handful of marginal options.
Ah, that’s definitely good to know. Thanks for the info Ed!
