At least I hope its not because I love using their products and I want Joel to do well too...
There's a good chance he isn't, though, because the company described in that article doesn't really bear a great resemblance to Atlassian.
The business models of Fog Creek and Atlassian are far more alike than they are different. Both companies are developer-founded, private, non-VC funded and growing "within their means". Both aim for bottom-up adoption rather than selling top-down through CIOs, and (although this is apparently changing at FogCreek?) neither have a traditional sales team. Both even started off writing an issue tracker (JIRA, FogBugz) then followed up with a content management app (Confluence, CityDesk).
Before this year we didn't have a growth strategy beyond "sell lots of software, and use the money we get from that to hire more people to make more software and sell that." We've recently got (temporarily) a little more aggressive about hiring because we figured the GFC was a great time for a profitable company to snaffle up any good people who were at loose ends, especially when some of our VC-funded competition were being forced by the same circumstances to lay developers off.
So yeah, we're hiring. http://www.atlassian.com/32/ :)
Jus' saying.
