On the Ask/Answer page you are using single-char variables in some places, e.g.
for {
r <- OutsideOfWorker on inst ask MooFu2("42") future;
v <- r
} dog = v
I recommend you give r, v, etc. meaningful names.
On the Skitter User page, shouldn't "Workers exist in finite, well typed classes" be "... exist for ..."?
And also on the Skitter User page "... supports the Ask/Answer paradigm such ..." could be linked to the Ask/Answer page.
Regarding the API: I suggest you rename (I love renaming, ;-) WorkerId.uniqueNameForFile to WorkerId.uniqueName. Maybe you will use it for a different purpose ...
I fixed two typos ... yes, I have got read access. Maybe you should check the security settings ;-)
Keep on riding the Goat!
