I think the loss of long tail is more to do with Google's incredible improvements in Adwords relevance matching. - internetheaven
Long tail traffic in most cases relies on internal link juice, this is how it works. - SEOPTI

More content being found? More competition?Same content, same competitors, have long been there in the index but never saw the light of day because our content was deemed better. Now, when ranked differently, they hit just the right spot.
New weighting of internal links, possible. But then everyone would be affected in the long tail field, thus canceling it out overall.I don't think it necessarily cancels out. All sites are different, at the very least in the number of pages hence internal links, and so the effect may be quite different on different sites.
Could be Google is now crawling deeper so found many new links, that might be throwing everything out of whack.I'm not sure if they crawl any different than they have been in the past but, with Caffeine infrastructure, they are supposedly able to take a better look at what's been there all along (and often is obsolete/erroneous by now). It may benefit older sites but it may not- if the old site had a lot of redirection errors/dropped URLs etc. - I have a couple examples like that.
Could be Site Speed was just introduced on more than a "test" basis.In the aftermath of the announcement I've done some speed tests and looked at a variety of sites and came to a conclusion that this may be the last possible reason you need to be concerned with. Not saying it's not one of, just that you really need to exhaust all other possible problems (which is impossible in practice) until site speed comes into play. I'm talking about a site that does not take a whole minute to respond of course.
Could be lots of things. IMO best to wait for the dust to settle.Don't lull yourself into passive waiting: just as success in Google breeds success via new links, viral promotion, bookmarks, feedback etc, the opposite is also true. Regardless of whether or not the site "deserved" the traffic drop in the first place, if you suffocate it without Google traffic long enough it will become irrelevant, obsolete and will further slip in ranks via "natural" ways - link attrition etc.
So, to everyone with the "long tail traffic algo change" theory, I have joined your club. Further to that, is there a correlation between gbot massively increased activity and loss of traffic, that is, while the traffic is at 10-50% of its usual, DEPENDING ON YOUR SITUATION gbot is busy hitting your sites, I appreciate this one question survey!
How can you see that google bot is crawling your site like crazy ?
I did not call May Day on this, but looks like it literally came whether I liked it or not, see the date of this post
Indexing of phrases is typically avoided because of the perceived computational and memory requirements to identify all possible phrases of say three, four, or five or more words.
For example, on the assumption that any five words could constitute a phrase, and that a large corpus would have at least 200,000 unique terms, there would be approximately 3.2.times.10.sup.26 possible phrases, clearly more than any existing system could store or otherwise programmatically manipulate.

giviz, eh bain alors, soyez le bien venu ici :)
I can safely add you to the list of long tail sufferers when I get back to it with a couple more people, as I can see your site/s more or less seem to have their data you provided almost fitting the equation.
Another short survey question for long tail problems - how many words long, on average, are the phrases that lost their traffic? Are they more than 5 words long?
In other words, until recently queries for long phrases may have had something like "best guess" results using some secondary signals -- but now Google has the infrastructure to index longer phrases much more directly.

Links! Links are out, content's in. Altavista won. Matt Cutts lost and retreated into self-imposed exile in Japan or Thailand [mattcutts.com] - whereabouts unknown. Google is to be renamed to Altavista promptly. Look for public announcement on Monday.

Don't want to just speculate - the implications appear to be too important.
I also hope for the second option, because it seems unlikely that Google would intentionally whack major websites with no guideline "issues".
