I peak and valley. When I first started commuting (6 wow years ago) I was very excited about everything. After a few months I started to trail off as subjects began repeating. Since then, I check in every 3 or 4 months for a coupe of days (but never post).
Also anytime I am shopping for a new bike or big ticket item I tend to pop back on. I'm currently shopping for a new bike, so I'm here again.
