As John Gruber pointed out last week, you can move your Yojimbo database into your Dropbox folder for real-time backup if you use a Symlink. For those who aren’t Symlink savvy, here is an Automator workflow that will take whatever folder you pick, create a symlink for it, and save it in a new location of your choosing.

This is commonly done to keep apps like Yojimbo or Things in sync across multiple computers. But I only use one computer so I don’t need to sync. However, I very much like the fact that now my Yojimbo database and MarsEdit drafts are backed up at all times, not just nightly.

Adam Schwabe writing about Gowalla (and Foursquare) in his 2010 SXSW highlights:

Neither application had been particularly useful for me at home here in Toronto up until SXSW, but that changed in Austin where they were great in tracking down friends and getting a sense for what was worth checking out at the conference and beyond. This worked only because I was a part of a very similar set of users with aligned goals, motivations and contexts for using the apps. I’m not so sure the usefulness of Foursquare/Gowalla will extend beyond SXSW unless you live in an urban area with a wired population; Like all social media, they won’t take off until your friends are on board.

The whole demo is with the iPhone using EDGE, and it’s fast. The app was submitted a few hours ago and Opera has a countup to when/if Apple lets the new browser into the App Store.

As Chris Forseman said about a month ago on Ars Technica, the reason Opera is so quick on EDGE compared to Mobile Safari is because “It sends URL requests to a proxy server run by Opera, which renders a page into an image that is sent to the phone for display. This method typically offers much faster browsing than downloading an entire page and all its resources and rendering it on most underpowered mobiles, and is especially nice for devices limited to EDGE or slower connections.”
