You can deposit less @moonprincess... The way it works is based on the amount you have on deposit... So if you have enough on deposit, then you will get the upvote... So if a smaller account only has say 1/2 or 1/4 of the 1 sbd, that is ok... they can send it in and it will get counted and the upvotes will occur...
The reason we set it for 1 sbd in the explanation is so that people don't have to think about it all the time and it will make it less cumbersome. For 1 sbd you get 71 dust votes of $0.028 and then you will be prompted to reload. But if there is a smaller account, then it is ok to send in less.
I'm glad you like it and understand the purpose, that is what we wanted to do is help the community (especially the newbies and minnows) :)
