Ask HN: Online undergraduate programs and graduate education?

I’m curious if anyone has experience getting into graduate programs matter having done an undergrad program online.

There are some decent online undergrad degrees nowadays, but when I look at graduate programs they tend to want letters of recommendation and many prefer at least some from academic sources.

But if you’ve completed you’re undergrad degree in an online program, you’re not likely to have built any significant relationship with any professors, at least not in a way they’d be comfortable recommending you.

Are online undergrad programs just no good if you want to be able to consider further education or am I missing something?
