Is it good idea to put out a placeholder site?

I was just reading this:

And it says:

Don't put it online before you have a quality site to put online. It's worse to put a "nothing" site online, than no site at all. You want it flushed out from the start.

What do you guys think of that? I was thinking it's better to put a site out as soon as possible, as soon as you register it, even if it's just one or two pages, so the domain can start aging and you can get out of the sandbox a bit sooner. But this guy says something different. So what works best?

Personally I don't think it matters. I've had sites with one set of content and even had different named pages running and indexed for over a year. Then I switch the content and the page names and it still gets re-indexed in the search engines with the new material. The only thing that I tried to do is to keep the theme (niche) the same. If my pages were about golf, for instance, then when I rewrite the site then it's still about golf just different info. And at other times I've just put up a page that says "mysite.com coming soon" and then that gets indexed, I don't know how it gets indexed because I usually do not submit it. When I do build a site then and start promoting it then after a time the "mysite.com coming soon" gets replaced by that content that's now on the site. Just my observations and opinions.
