thanks for the post! i have some questions :-)

will it cost in the future?
how long are the delay? i mean how long does it need from steemd into the mysql db? how often is the db updated?

Can i use this for our notifications in steempi? that would be awesome. Are there any limits? query limits, time limits etc?

at the moment i made a bad hack to get reblogs for our giveaway :D so hive would help, too!!
