mybatis’ homepage has this quote
mybatis, the world's most popular sql mapping framework
There are only 16 questions on StackOverflow about mybatis, compared to 5,299 on hibernate. Look at Google trends. Are they completely BSing, or am I missing something (red is hibernate, blue is ibatis)?

myBatis is a successor of iBatis, that’s what they meant saying
on their homepage. So, the name iBatis is more widely known, ibatis contains 204 questions.
Also, as mentioned by duffymo, it’s not an ORM.
