You are welcome. Next summary either around 1 September (3/4 duration),
or after passing number of responses in previous survey; it also depends
when I would have time.

Well, you can do some analysis yourself, using just created filters at
http://www.survs.com/shareResults?survey=2PIMZGU0&rndm=678J66QRA2
For example:
================================================|
| proficiency with Git |
To learn |-----------------------------|
| any*[%] | 1-3 [%] | 4-5 [%] |
------------------------------------------------|
Very easy | 4% | 3% | 5% |
Easy | 20% | 19% | 22% |
Reasonably easy | 55% | 55% | 56% |
Hard | 19% | 20% | 16% |
Very hard | 2% | 3% | 1% |
------------------------------------------------|
Total respondents | 3005 | 1786 | 1212 |
================================================|
Footnote:
^^^^^^^^^
[*] This means no filter, which includes people who didn't answered
question about proficiency, but answered this one.

Here also you have to be careful about the fact that "correlation does
not imply causation" (or, if you prefer Latin version, "cum hoc ergo
propter hoc"). The causation might be both ways: gurus don't find
git hard to learn, or don't remember that it was hard to learn; people
who find git hard to learn do not become git gurus.
