You miss one or twovimportant ponits, tho. Firstly when trying to get something trending like the Wow petition the RT has to be manual, as Rts dont count for trends, it has to beanew tweet. Some people are on private accounts, so the RT has to be manual. Lastly, and this is perhaps the most dubious,ihave noticed that stuffimanually RT gets signal boosted far more than stuffijust RT, althoughIdo tend to H/T or M/T rather than RT.I dont think it is just news tweets who get the endorsement thing. We all follow people because we want to know what they say, something they tweet catches our eye more thanaRT.
