I have coined this term - well there is a tool by that name but I can still say that this is term for "furthering your opinions under the garb of a blogger".
Now back to BPM - BPEL is not for humans- this is a thing I read on many blogs. However nothing can be farther from the truth. BPEL is extensible by nature, it allows a process developer to call out to any standard workflow service and create a Human Task. On completion the workflow server can update the process back / BPEL process can detect that the task has been marked complete and carry on the execution of the process.
Thankfully, there is a spec BPEL4People to answer all the acronym happy analysts and bloggers!
