When the customer demands a project specifically using WordPress.

At least not Joomla. aaaaaaa

"let me recommend you to a friend of mine, he charges more than I do but he works exclusively on wordpress"

From an end-users perspective, what's so bad about WordPress?
I know it can be a pain to maintain shitty plugins or themes but if it's setup most of the dumbest people can use it...

... on the other hand you haven't mentioned what the customer wants to have. If it's too far from a simple blog/homepage it might not even be simple to use anymore.

@thaelgar even from a end user perspective, if it got out from the a plain blog site, it starts to be mess

That's why I use bolt cm, I have a client that always asks me two quotes, one using bolt, and the other using WordPress. Bolt is always cheaper to develop

I got to administer a few pages and WordPress went pretty well on the customer side. But it's just used to enable the user to self update a bit of their content. Perhaps it really depends on the complexity of the site.

I didn't know bolt (I'm not doing this for a living :) Looks nice but I suppose there are a lot fewer templates and a way smaller dev-user-base, right?

@thaelgar they don't have templates "at all", but their templating system is pretty simple, so it's easy to implement any template, WordPress always need a lot of files for a lot of things, bolt is pretty simple in this side

Seems like it's out for me. Starting to implement templates on my own is to time/money consuming for me to do this for smaller sites.

My HTML templates are generated in C++ 😎

Download a theme and give to him :)
