Do it, Luck. I use my S100 so many times through out the day. The $500 I paid almost a year ago has been worth it already. Having your own blog is neat and it benefits yourself the most since it gives you the chance to reflect and voice your opinions. At least that's how I feel.
If I can go back in time, I would definitely blog my weight lost process with my routine, diet, etc.
Yeah, bro. There are trolls online and in real life. You just gotta ignore them on both segments and continue on with yourself.
