This is an important lesson and one of the reasons first movers are not necessarily winners in the end. Too much focus on technology and/or too little on user experience.
"Robert Morris from IBM argued last year at Etech 2002 that -- and I'm paraphrasing from memory here -- most significant advances in software are actually advances in user experience, not in technology. Mosaic was not an advancement in technology over TBL's original browser. Blogger is a highly-specialized FTP client. IM is IRC++ (or IRC for Dummies, depending on your POV). The advantages that these applications offered people were user experience-oriented, not technology-oriented."
