Currently such votes seem to be worth less than 0.01, not sure exactly how much.

There is work ongoing to remedy the problem, as it is a bug caused by the algorithm assuming history (which we don't have yet).

Presumably we would want to see a situation where 1000 blurt can tickle a reward by 0.1+

The current curve and its constituent constants clearly don't produce this effect. For the time being there is a few roving whales dropping some 0.1-1.0 sorta level upvotes.

There may be a second hard fork to tweak the parameters that calculate the rewards to bring them up to a more reasonable level. The rewards should be pretty nice once it's fixed, we reset the inflation rate to 10% at genesis so it's higher than the 8% or so in force on Steem and Hive chains.
