Hey folks, new here and happen to also be a LAMP developer (not considering creating an exchange yet 
...
I just wanted to jump in here and defend LAMP stacks.
Linux/Apache/MySQL/PHP (LAMP) CAN be highly secure depending on how the code is written.
This forum runs on PHP, most major banking site's fronted is PHP...
The problem comes in when people write insecure code, you can just as easily write insecure C+ or Python as insecure PHP...
I guess my point is dont bash the platform, bash the developer

I agree. I'm getting a bit tired of people who language bash. For example, DeathAndTaxes, whom I respect is killing MtGox in this thread, but he hasn't once faulted the language of choice. Often people who bash don't have much achievement of their own which they can point to, which is telling.
Mysql? php??? For a multi-million dollar website?!?!?!? WTF!!!
Umm, Facebook was built on PHP and they just bought a company for $19 billion. Magento, also built on PHP, was bought by eBay for $180 million. Which apps have you done lately that are worth millions of dollars?
A good programmer can usually do well with most any language, although some may be better fits for a given application. It depends more on style and preference, which is why Google, which probably knows a thing or two about software, allows people to write in the language of their choice for their annual Code Jam with $15K prize. They are not so ignorant as to think various programming languages, which are just tools, can't be used effectively.
