damn you were right. It works like this, the delegator doesn't get a curator reward. Damn I always thought it was different but I haven't used this mechanism in practice.

Now I'll have to figure out some way to pay out rewards to investors. Fortunately Mariusz was aware and wants to leave his delegation so the community will be able to enjoy the support of a bot with quite strong votes.

Nevertheless I'll answer your question why someone would want to support such an initiative anyway. Because such tools make blurt attract more users or give meaning to being here to those who are already there. They also make it much more meaningful to build your blog here and your content can be rewarded even after years. So ultimately it's for the benefit of the entire network and as a result the price thanks to such solutions increases.

Such delegations wouldn't have to be big but let's say that everyone here would delegate 5 USD to each tool that supports blurt. It's not really a fortune, but if you multiply it by 500 users, you have 2500 USD BP, which serves the entire community, while the author of the tool is paid. Remember that in order to create something like this, I first had to devote several dozen hours of my time, I didn't do it just for charity. Maybe I don't expect a fortune, but it would be nice if this time paid off someday :P So, to pay someone's work, you can delegate them some of your funds, so that through the % of this sum that they gain from operating the tool, you can pay them for the time they devoted to developing the network.
