There are downsides to the toolbar, one of them is that google knows about urls that are never linked.
Some sites use unique per-user access URLs as their only access-control; I would have expected more tales of woe if such URLs regularly received Googlebot visits or appeared in search results.
This led to a lot of trouble...
Since then no more google toolbar for me. Google denied involvement, we later figured that it might have been an adsense or analytics tag as well, but there are supposedly no flows of data between those projects.
The damage was done, the page should have been password protected, we learned our lesson and moved on without spending a whole lot of time on finding out if there may have been another cause, we couldn't see another one that was likely.
There are plenty of other cases like this on the web, Google has always denied any kind of flow from the toolbar or adsense/analytics to their search crawler.
One thing I do know: if you are building a website and you have adsense tags on the page you can not password protect it and expect to receive relevant ads because the adsense crawler can not reach your content.
AFAIK the best workaround for this problem is detecting the bot and presenting a different page (or at least one without a log in).
The google toolbar license ( http://tools.google.com/tools/firefox/toolbar/FT3/intl/en/in... )
contains this little tidbit:
"Google's Search Service Google Toolbar is designed to be used in conjunction with Google's search services. Accordingly, your use of Google Toolbar is also defined by Google's Terms of Service and Privacy Policy. "
And nowhere does it explicitly state that the toolbar data is not used to enhance the search engine results, personally if they had no other use for it as a discovery tool then I would wonder why it was made in the first place.
If google does not use the toolbar data in any way then it would be a small matter for them to say so loud and clear in the toolbar license or their privacy policy.
<uniqueID>.something.com where something is setup by the camera makers to provide an easy way to share your cam. (This isn't anything new, I was thinking of doing some analysis on all the public IP cams you can find on google a few years ago).
Here's another one http://www.google.co.uk/search?hl=en&q=inurl%3A%22snapsh...
After the 1st page or so, the rest are all Panasonic IP cams.
I think the answer is to have IP cam makers default to private - just like routers/hubs/etc
They're such useful tools in arguments.
Of course, if you already agree with a speakers' point, the analogy makes sense and helps make the matter vivid.
But when a listener intuitively disagrees, the analogy can derail discussion. Even though in the spirit in which it was offered, it aligns one axis of the issue at hand, with one axis of the offered analogous situation, the listener instead may focus on -- and comment about -- every other dimension of the two things that are wildly different.
For some thinkers, all those other differences are easy to factor out -- of course they're different in those dimensions, and the wild variance only serves to highlight the similarity-in-one-dimension-of-interest. But for other fuzzier/holistic thinkers, every difference is a distraction to be considered separately, and the attempted analogy may harden them against your point.
Worst case is when some other aspect of the analogy so dominates listeners' thought (or can be cynically flipped against you to imply you've said something you didn't mean). This is why Nazi analogies can be so conversationally-derailing -- whatever one small comparison was being intended, the response is "how dare you call [Bush|Obama|Teachers' Unions|Evangelicals|Mall Santas|etc] Nazis!"
