Everything that DC does these days blows my mind. Obviously, nothing will top how they've totally mishandled 25 years of brand-identification for Wally West as the Flash, but the change on Robin is almost as stupid.
Jason Todd was Robin from 1983 until 1988, a total of 5 years. Tim Drake was Robin from 1989 until until 2009, a total of 20 years. I personally own every BATMAN and DETECTIVE comic including Jason Todd as Robin from the time period, and I also own every BATMAN and 'TEC during Tim Drake's run in various ROBIN series. Were I to put the two on a balanced scale, the scale would fall off the table in favor of Tim Drake.
In order to correct for having too many Robins in play at one time, a mistake that DC can only blame on its own editorial staff, the company has chosen to turn its back on fans who have made Batman and Robin the company's best selling characters to support a cascading series of bad decisions for the New 52. I think that's an incredibly short-sighted decision considering there is an established fan-base that has eagerly consumed over 200 issues of Tim Drake as ROBIN over the past two decades.
What we Booster Gold fans are really fortunate about is that Booster Gold isn't a legacy hero or one of a series. If DC thought replacing the man behind the mask would make some news, they'd do it in a heartbeat. (I'm sure it helps that the original creator is still involved in the business. That has to help keep Booster involved in the DCU without succumbing to the whims of a writer/editorial staff who would sacrifice the core of the character for a short-term gain.)
