I think this is simple advice and often incorrect.

For example: JIRA, it's very complicated software. Many of the complicated features I think are essential for it to get into the Enterprise market. Revenues $242 million.

Basecamp: Their mantra is simplicity (although they do not actually do just one thing, they have several features as part of their software). Revenues estimated at over $100 million.

I do no think there is one simple answer to how to build a successful startup. Focusing on being great at one thing might be a good idea for some businesses but it's not only way to do things and it's far from proven as "the" way to build a startup.

In a sense, the "one thing" that JIRA does really well is being bloated (and through fulfilling the check box process).

And I'm only half joking. I mean, have anyone ever successfully been productive at using the thing? To me, it certainly doesn't do well in department of being useful to developer (or manager, for that matters).
