How do you see the cult of multiple founders? (who, however, leave their businesses abandoned)

Over the past month, I've been scrolling through several LinkedIn profiles and noticed how some people have long portfolios of businesses that say:

– Founder

– Founder

– Founder

– ... (but they've been at each thing for maybe half a year and are already starting something new)

How does that affect you?

I think it's great to have a strategy for shipping things quickly; "you only miss those shots you won't take," but doesn't it seem bad that a person doesn't know how to properly scale at least one thing?

Because when I see this repeated 6-10 times without results, it also has some telling value.

What do you think about this? Is it appropriate to put it on your LinkedIn profiles at all?

Since I have been spending 6 months pretty actively on LinkedIn, I am trying to understand how to polish the profile as best as possible.
