Many projects explicitly look for freelance WordPress developers, it's a huge market and I respect it deeply, but I'm glad my career put me in a position where I can totally ignore it.
There has to be something like Wordpress for Web 2.0, so we can break the oligopoly of Facebook, LinkedIn, et al. and move the world from digital Feudalism to a Free Market:
So they stuck with Excel, even when they had access to a programmer.
Programmers can laugh all they want at Excel, Wordpress, PHP etc - but these are tools that get stuff done quickly and make businesses a ton of money. So businesses will continue to use them, even if there are much superior tools around.
I don't laugh at them. I see many people more clever than me working with tech I don't like, and making more money than I make. It's completely OK. I even wrote some PHP lately, and while my humble opinion generally hasn't changed (that I'm too dumb to use PHP), it's clearly VERY fast and easy to get started, while there are many people throwing money at you when you are good at it. If you are competitive and can work with weird setups (which is a given for many customers seeking freelancers), and under stress, then why leave money on the table.
Some may take what I'm saying like a snipe disguised as humility, but I'm completely honest. No sarcasm at all.
