Caveat: I'm unfamiliar with the US/EU status quo for this category; maybe there are better options in those markets?
Your mileage may vary, but as a WASPish male mid-level dev based in London, this is true for me. I can appreciate that people outside that circle may get more value from LinkedIn.
LinkedIn on the other hand gets me maybe one offer per month on average.
I also have a blog at http://henrikwarne.com/ but I have never received any job offers via it.
I go to very few meet-ups, but the ones I've been to have never generated any offers. So in my experience, LinkedIn wins hands down in that respect (I'm in Stockholm, Sweden).
Maybe they found you on LinkedIn :)
I remember trying to figure out how to unsubscribe to emails from (I think) careerbuilder a few years ago and it was an absolute mess.
>>> maybe there are better options in those markets?
One site that seems most nimble right now would probably be indeed. They are growing a lot particularly here in europe and are more flexible in their partnering agreements. I work at the moment for a SaaS recruiting product, and I know all the big players are a pain to work with for integrations.. just reams of red tape.
Another thing that is far more common in europe is that the job sites are much more fragmented. There are so many craigslist type sites that are driving lots of traffic that recruiters want to integrate with.
