If you have spare time you should check out this review of

Yotsuba&!'s current translation:

It goes into detail about the pros, but mostly the cons of the overliteral translation of Yen's version.

William Flanagan translated Kobato, and thus far he's one of the best! The series he translates are treated with that great sense of accuracy he always has:) Not meaning to be offensive or anything but some translators who have a number of series under their name don't always do a great job like Will. Take for example the translator of Haruhi, the translator has a lot of series under her name and yet Haruhi manga ended up being over-literal and poorly adapted into english.

P.S sorry for the long speech but I'm just a fan who cares to read before hitting the click to buy:)

I didn't realize some readers were disappointed with Yen Press's work on Yotsuba&! – I thought it read really smoothly and didn't seem any less hilarious than ADV's version. I will agree wholeheartedly though that Kobato was very well done, very fluent and cute as it should be.

I`m hoping(with a lot of other fans out there) that Yen doesn`t skim down on the quality put into Uraboku. The Haruhi manga translations were one thing, but the Yotsuba&! translations were just a plain disappointment. Which is why I'm hoping for the same signs of quality and effect as the guys who translated Kobato or Parasyte:) *sigh* For now, *crosses fingers*
