Quite Useful Weekly Roundup

This week I started a new series called Let’s Make a Game.  I’ll be continuing this series next week, with posts about how to add rules and maps to the game.

We also published a series on open mapping technology: Introduction, OpenStreetMap and OpenLayers.

Here’s the Twitter roundup.

Social

TweetChat makes Twitter feel more like a chat room, grouping posts based on hashtag.

Hunch.com launched with a closed beta.  It helps you make decisions using an almost 20 Questions-like algorithm.  I’m on the beta and it didn’t take long to get accepted, so it’s worth putting your email in.

BlueBird is a cool new Mac OS Twitter client.  It’s native so the interface feels fast, and looks good too.

Design and Developer

Product Planner looked like an interesting idea.  It helps you design products through “user flows”.

There’s a Palm Pre developer preview out which looks interesting.
