"on python-list and probably elsewhere"... I can confirm these questions get mailed to webmaster@python.org :)   A couple of comments since I see these fairly frequently:

The "using" doc page may have too much information for beginner tastes, but at least it answers a lot of questions. but it's hard to find... it would be nice if the OS-specific installation page actually pointed to it - or to a more concise alternative if that's preferred. Applies to Mac as well, as most people who install on Mac seem to have some surprise with it not launching the way they expect.

Proposed text: "If you want to run Python, press Start and find 'Python 3.x' under 'P', or enter 'python' in the "Search for anything" box on the taskbar." - why not mention the Python Launcher here? Isn't that the preferred approach now for the pydotorg installer?
