Good and valid question. I know of the following two services which are quite similar.

### [Steemauto](https://steemauto.com/faq.php):
Steemauto only offers trailing, no specific upvote rules for authors, with regards to voting. They do offer interesting other features.

### [Steemvoter](https://steemvoter.com/)
The main focus is personalised voting rules here, which is a similarity. However, they do not offer Steemconnect intergration, so the service requires you to give up your posting key. This is not good and outdated. Also the rules only allow for upvote weight and time delay. No daily limit for each author

>How is that different from Steemauto and other services that do the same? Seems like a waste of someone's time.

I believe this is quite narrow minded, competition is healthy. And will propel these services forward.


>  Seems like a waste of someone's time. Is photography not lucrative enough?

Photography has never been my main source of income. It is a hobby and will actually be getting into videography next week for cliff diving in Greece. Besides that, the service is free...

Also, 

>waste of someone's time

Learning new things if never a waste of time, even if this means learning something that is already out there. You start small and expand from there. Live products are great use cases to see how something really works.
