Relatively speaking, the time someone would need to spend keeping their LinkedIn profile reflective of their career vs. learning/coding/solving is negligible. I've spent 10 minutes in the last year, for example, entering a promotion. LinkedIn's value, and arguably it is aging, but that's also the point, is retaining opportunities for future endeavors. This is for me a much larger value than advertising my CV. To wit: LinkedIn literally saved my company during the housing crisis. It was during the act of connecting with former colleagues that I got a lead for a major project that wound up being 50% of our revenue in 2009. Moreover, as time goes on, the folks connected with gain promotions and grow their careers as well and you can wind up with a rather impressive Rolodex[0] of contacts. It's worthwhile to keep your profile up to date, and does not take a material amount of time. [0] https://en.wikipedia.org/wiki/Rolodex https://en.wikipedia.org/wiki/Rolodex
