Is there a worse second level for a class than Sorcerer? +1 casting per day of a 1st level spell and +1 known 0th level spell and that's pretty much it. I think every other class gains some kind of class ability. Maybe the bloodline spell should be brought down from 3rd to 2nd.
And on an unrelated note, Adding in an extra class skill with the bloodlines to a class that only gets 2+int skill points per level isn't helping much. I'd suggest either granting additional skill points or giving free ranks in the bloodline skill rather than just allowing it be a class skill to be bought.
Well I imagine the sorcerer gains the bonus spell at 3rd level so there is a regular progression... every other level after 3rd.
But second level is pretty anemic. Having either the bonus spell or the bloodline power at second level would be a good idea to round out the class.
I agree with your sentiment.
Now that there's so many different "aspects" of the Sorceror (Normal Spells, Bloodline Spells, Bloodline Powers),
there should be SOMETHING to add at that level. As is, they're just getting the minor bumps ANY class level does (hp, saves, etc) and a cantrip. Having 2nd level be so "dead" really makes a player more likely to just one-level dip in it, unless they've already decided it's their main class.
About the Bloodline Skill thing, check out this thread I started on that topic...
I think they need something bloodline powers would be sweet
