happy to be back on tip.it, took a break... well, in the first article, i didnt understand where the author was coming from. there seems to be a whole lot more medium and low level content and updates than high leveled ones. well written but i dont agree on most of the points. the second i really enjoyed. great to see some tested theories put into an equation. some of the terms used were not the universally accepted terms but since it was explained so well, that didnt matter. had fun reading the times, just like i do every week =D>
