I have also seen similar language on other sites, but the the sequences are a lot longer than what I have seen other sites asking new visitors to read.

I had read OB when EY still used to blog there, so I read a lot of the sequences at that time. Stretched out over time like that, they don't seem as long. But for a brand new visitor, the sheer volume is somewhat daunting. That's why I think more nuanced suggestions, perhaps like Jack suggests here, might make sense.
