Ok, so the guy came and asked, I was ready to deliver but he deleted his post before I could hit send. Having it in my clipboard, and being a bit mad about the deletion, here it is guys. Take note the guy didn't want to do startup and had programming background:

in Wordpress sites (which hopefully I won't have to deal with ever) (they'll ask for Photoshop, PSD-to-HTML conversions etc)

Ok, no matter what you do, unless you live in a cave and work for old backward web business (the kind that tries to do webforms-like applications) you will definitely have to deal with one of those if not both... Now, as for languages, they are more or less equal in basic functionality, you basic application need will be taken care of. PHP is pretty much the go to for any project as it's established and any and all servers can be used instantly. Ruby is having a great boom, thanks to the powerful Rails framework but is still something that the kind of customers you might deal with (with the description of what you want to do) might be cold to go with. Python I have no idea, never really seen a line of it in my life... Node.JS has loads of great opportunities right now because it's the hot shit, but at the end of the day, I, personally (in my opinion) think it's gonna stay that way for anything other than real-time web (chats and whatnot). ASP.NET is a great platform to devellop, it might feel secure for you, the problem is never in the the platform but in the businesses that uses them. Most of them are in the old backward web businesses categories. They know how to do great code, but then they know jack shit about the web/html/css/js standards and you end up with shitholes that look like they were coded like 20 years ago...(I had to deal with one recently and let me just say I cried a lot and bled a little... 180 javascript files loading with the web page... 180!!!)

This may be opinionated but you cannot avoid completely working with things like HTML and CSS and Javascript to a degree, I mean you want to work with the web and those are the most basic building block. But unless you apply for a front-end job or designer job, your ratio of time passed using photoshop and doing PSD->HTML conversion will be really low. There are plenty of back-end job at medium to large businesses, you could even go freelance and approach design agency and ad agency to do the programming for them.

All in all, I would propose you go the php route, learn a bit about it, then find a framework you think seems interesting (if you want big corp, go with things like zend but otherwise I propose Laravel, it's like a girl in a gay porn, you never stop looking at it and you don't want to) and also learn a CMS (Wordpress is a really good one, it is surprisingly versatile when you start working in the code itself, Drupal is even more versatile but it demands more dev time to do some things WP can do out of the box) and also a e-commerce platform (even if it's the worst piece of garbage for devs, go for Magento, the brand recognition speaks for itself and it really is powerful for small and big shops, otherwise use the CMS plugins like WooCommerce or Drupal Commerce) and you're set.

(Notice how I have not mentioned Java? yeah... that was not a mistake...)

That's my opinion, being in the biz for nearly 4 years. Also, I'm in Canada, so some of what I said might be different for you or whatever, you know where this disclaimer is going...
