There are so many factors that can boost a newbie beyond level 50 really easily and curie alone makes a massive difference, but paid votes can do it too. The move to level 55 has really helped with allowing everyone to find people that have shown a little more commitment to sticking around.
As for the optional featured blogger, that is an easy one to add back into the mix. Felt like it wasn't really being used much except for a couple people. But it's optional and if even just one person likes it there is no reason not to have it.
Hope everything works out at the dentist!
