Here is a rant from me ... there is no effortless way to put mysql results into map [string]interface{} (equivalent to mysql_fetch_assoc) with built in typing. You get []byte and have to cast and scan everything yourself. Also go is hard to serach for in google and google groups where golang nuts are - they are as pleasurable for searching and finding info as a kick in the balls.
Apart from that the language is very solid and has some nice decisions made about it.
