I am wondering whether it makes sense, is acceptable, and/or advisable to have a 2nd LinkedIn profile for yourself if you have both a professional career and also a side business for which you're an entrepreneur? For example, if you are a software engineer with over 15 years experience and a strong reputation, and also are starting a startup, it seems inadvisable to advertise that or even make it known from your regular LinkedIn profile, if only because it dilutes the seriousness of your professional determination. I don't mean to suggest one should be dishonest, however it is surely the case that one would want to hedge against the failure of their new enterprise by protecting their professional appearance, and not let potential employers think that one might just be about to quit the industry.
I'm not sure what LinkedIn says about this, I've seen a lot of accidental double accounts, and I can't tell that they really care. Perhaps their TOS are more specific, I haven't read them yet, and probably should have prior to posting, and will now go do so. But the question still has merits in a general sense, even if LinkedIn forbids it. How does one deal with this challenge?
