Let's add a dose of perspective here. Do a job search on craigslist or simplyhired for "php," "rails" and "django" and you'll see that there are vastly more PHP jobs than either (10,726 on simply hired right now) and many more Rails jobs than Django jobs (2,553 vs 328). Django is popular with some circles, such as people reading HN on Saturday nights (which is when that poll was posted), but this does not reflect actual usage.
"Current PHP openings are more than likely for legacy web development."
That's quite a massive assumption. If we do a job search on startup-specific job boards, (like startuply.com and startuphire.com), you'll see the same sort of thing. On Statuply, "php" returns 280 hits, "rails" 121 and "django" 35. On StartUpHire, "php" 458, "rails" 119, "django" 9.
Long story short, don't believe every poll you read on the internet.
Also, don't take this as me talking bad about Django; it's a great framework and programming is not a popularity contest.
