What duiker101 said. I built a bookmarking app when i was first starting out as a programmer because i got tired of losing mine every time i had to switch computers. This was before chrome. I have since written it over every time i learned something new. From asp.net 1.1 with datasets to asp.net mvc 3 with nhibernate 3.2, this thing has been a great continuous learning exercise. The fact that i could use some other product does not factor in to it.
