I will admit that the spell-checker has been a godsend for my writing. However, recently I found a great browser add-on that catches my typos on the fly. Linked above, Grammarly catches my typos, punctuation mistakes and stylish inconsistancies. My only concern is that "smart" technology seems to keep making us dumber. Once spell-checker came along, we no longer needed to know how to spell everything. This closely resembles how math skills have gone down with the advent of calculators. And, likewise, perhaps my grammar skills might take a dive if the computer covers for me. I'm using this technology, but with some concern.
