Taking your bike on the bus is great -- I sometimes do it myself.
But bus bikers, *please* get out of the way of the bus after you take your bike off the rack. Don't get on your bike right in front of the bus and then start riding slowly. The 30 other people on the bus just waited for you to take your bike off the rack, so it's the least you could do to let the bus get moving again, and maybe catch the next green light.
You'd think the second person who did this would have noticed how annoying it was when the first person did it.
A separate thought: now that the bike racks are getting more popular, what will happen when a third biker wants to use it once both slots are full, and the next bus isn't for an hour?
Stay tuned for the next rant: people who load $1.25 on their Charlie Card using the bus farebox, *every single trip*.
