Too much interruption is bad, I agree, but there are some type of skills / mindset that are 100x times simpler to gain by contact with colleagues than by training on your own (even when looking at forums). Especially on the things that you wouldn't not think about improving. I had the luck of working with a dude who was extremely good at analyzing data, simply by loading json files in sublime text, doing a mix of pretty-printing, multi-cursors changes (with usually 1000+ cursors), regex-foo, playing with buffers and other linux commands. It was a weird set of skills that was truly magic to behold, and not amount of Youtube conference or code review could have replaced that. There are some coding livestream that can help with that, but it's not as efficient as being in the room as talented peoples.
