Austin's startup scene is vibrant, maybe even frenetic. I find it challenging to stay on top of it. Fortunately, there are some slammin' sites and terrific tweeters to help. Here are a few that I've found.
"Intro to the Austin Startup Scene" by Damon Clinkscales
OK, I'm cheating a bit here, because I only found the next two entries on this list from this super-helpful presentation on Slideshare. It's chock full of essential resources. Check it out, and then follow @Damon on Twitter.
austintechmap.com breaks the startup scene down by geography (obviously), as well as the type of company. It includes VCs, coworking spaces, and a list of who's hiring.
This really really big list
austinstartuplist.com is what it sounds like: a list of over 1700 startup companies in Austin, and it's sortable by metrics like website traffic.
Austin Startup: news, jobs, & more
austinstartup.com is a good resource for breaking news coming from the startup scene, and you can subscribe to get news via e-mail. The site also has a jobs list (which unfortunately doesn't appear to be working at the moment) and a short list of other sites/resources.
Austin Startup Digest
This is really a two-parter: Startup Digest provides a "personalized insider newsletter" that you can tailor to specific interests and cities; and, Joshua Baer of Capital Factory fame curates a helpful calendar of startup-related events. If you use Google Calendar, you can easily subscribe to his startup calendar and never miss out.
I'm sure there's much more…
