For those of us who aren't in the percentile that can afford the time and $$$ to attend an ABA LS (time is most likely the greatest factor), YES, DL is a viable avenue to pursue a law degree.
Career development and self improvement may be the main purpose of DL learning. We may not WANT to become a practicing attorney. We may already have career paths in which a non-ABA JD degree can only assist in our journey. There are those who say, "Aren't you all just wasting your time & $$$?", and the answer is most certainly...NO. To interject that blanket statement with the assumption that it covers everyone in every situation is completly asinine.
I agree with LawSchool@40 & GovLaw in that everyone embarks on this journey for different reasons, but without truly knowing the reasons behind the decision the quoted blanket statement cannot be true.
