No the real issue is not the gaps themselves but why so many different jobs that don't last long. Tech evolves fast but in a week or 2 you're up to date if you've been away few months. I have many gaps in my resume but I have many different jobs, which is a lot more problematic. A question that pops up often is why did I left after X months and I need to explain all my choices. It is fine because I either didn't like the projects/companies, I wanted to switch technologies ... they do ask why 6 month off and that seems fine when I tell them I've been travelling.
