You appear to assume that obtaining clicks from HN readers through subterfuge is the author's goal.
I don't think that's borne out by the content of that post or of other posts. It's more likely that he's just writing for his regular audience, for whom the title expresses exactly what's happened: he's changed the operating system on "the Workstation" to Linux.
I should apologize, I submitted the article with a different headline: "Joyent sysadmin switches to linux". I contemplated using Ben's full name but I thought better of assuming everyone knew who he was. My title was an attempt to summarize the article, which I will avoid doing in the future.
For those who do not follow his blog, Ben was a major OpenSolaris proponent and even served on the council before the Oracle buy out. I never thought I'd see the day he replaced a solaris machine with linux.
Now I should also mention that Ben thought Sun got distracted by focusing on OpenSolaris as a OS for developer workstations. Thus I think it would be inaccurate to call the OpenSolaris forks dead, I'm sure he still prefers Solaris on servers.
I actually prefer your headline because I think it gives context to the post. Joyent has been promoting Solaris in a world where everyone else appears to be using Linux.
