Glad to see the @webengineshackfest.org covered in the local tech magazine @codigocero.com. Of course I’m biased, but I’m very happy with the growth of the event and the really interesting discussions that happen there every year.

One of the takeaways from this week at @webengineshackfest.org is that standards and browser engines folks are moving way faster than I assumed, that is quite incredible given how many stakeholders and points of views need to be taken into account at every step.
