I prefer the first method, but sometimes the second one is necessary. From you earlier thread, if I were you I would stick with the first for now, unless you have one article related to another “coming soon”. If that is the case, best case you would tell your reader when “soon” is. For instance, “See Part II of This Article next week”
I find it quite aggravating to click section after section of a website to be faced with “coming soon” every which way I turn.
In terms of user impressions number 1 is, IMO, better. As shyflower mentioned, “coming soon” is an annoyance and in my opinion is rather unprofessional.
In other words, I prefer the ‘launch with a bang’ method - which applies to both websites and individual pages.
I’ll join the others and say stick with #1 unless you have a VERY good reason not to. Not only is it confusing to users, but it just makes you look bad. I tend not to go back to sites with “coming soon” as I can just as easily find the content elsewhere.
I like the option you didn’t mention: “Coming Soon… pre-sign up!” version, e.g. this one I’m workin on.

(It’s for medical use… just fyi)
This option allows you to have a pre-launch splash announcing your plans, pre-sign people for reminders of when you do launch, and a countdown building up suspense.
It’s good all-around… gives Google a heads-up, potential users a heads-up, and lets you pre-build your database for a good seeded launch!
Integrating with Facebook connect allows you to pre-advertise to your social network and get a chain of people connected / signed up without much hassle to them.
I also prefer #1, for the reasons given by Linda and Jake.
This doesn’t mean that you can’t already lay out your website with all categories/sections/pages, just don’t show them to the public until they’re ready
Google doesn’t care if you ever publish anything on your blog. Their bots will pay scheduled visits to your website whether you do on not. Their primary concern is to help their end-users, your potential readers, find that for which they are searching. Those pages that are “coming soon”, “coming later”, or “coming never” all have equal weight. Zero.
