Ask HN: What do you think about dev webinars?

I am working on a very ambitious platform for web development. I believe we have a great product. I am planning strategy to spread the word about it.

I am considering a series of webinars targeted at developers (the kind that reads HN). But I wonder how many devs attend webinars at all? Maybe it is better to just focus on producing quality blog content instead.

Being a dev myself, I have attended maybe 3 webinars in my 10-year career.
