Less votes per day does not mean each individual vote is worth more. A users vote worth is relative to the amount of Stake(SP) they have.
The way the platform is, it's to give the incentive to increase your stake. So if you want your post more visible then you would need to find ways to get more SP or those whale votes. At the same time, this is a blockchain. So there is nothing stopping someone to pay another person with a lot of stake for a vote or collude.
1 post read by many does not necessarily mean the work is of a higher quality.
Yes, commenting and reading post is not considered as valuable as it should but they do still hold value.
Basically, what you said at the end, Time will tell.
