It seems that the question on everyone’s mind over at SXSW this year is: What will be the next Twitter? Well, as our own Pete Cashmore said the other day during an interview with Bloomberg, and during a recent interview with’s Dan Fletcher: It’s all about location.

Twitter still remains a SXSW legend, even though some point to stats demonstrating that Twitter’s web traffic has been leveling off as of late. Still, the microblogging site asserts that it’s going as strong as ever, arguing that the true rubric for success is the number of tweets being sent out as opposed to the number of people logging on to Twitter via a web browser.

Now, location-sharing services like Foursquare seem to be creating a ton of buzz down South. Foursquare was first introduced a year ago at the SXSW conference in Austin, TX, and has only become more popular in the ensuing months — just the other day it garnered 347,000 checkins in a single day (mostly due to folks checking in in Austin). Other services like Gowalla have also joined the fray, as well as Facebook and Twitter, who have adopted or plan to adopt location features.

Check out the video below to see Pete chatting with Time at SXSW about Twitter and Foursquare, as well as how Mashable was born, the evolution of social networking, and what trends Pete sees dominating in 2010.

What do you think of the future of Twitter and the advent of location-sharing services? Let us know in the comments.
