Every picture on Picapp has a small control at the bottom of its screen that lets the view assign a star rating – 1 to 5 stars.

Picapp Rating
It’s a good idea and I want to have something similar on this blog. Actually – there’s a problem but I’ll talk about that later.
I clicked on the question mark and found out that the rating service is provided by a third party – Outbrain.com.

Picapp Uses Outbrain
Oh no, it’s a platform!
It looked like I could sign up with them and add a similar control to all my blog posts. Then readers can tell me what they think of the post with minimal effort.
BUT I found that …
NOTE: The widget is only available for the installed version, and not for blogs hosted on WordPress.com (yet). If your blog is on WordPress.com, you can help us get approved there by giving your voice.
I went to the link indicated and found out that people have been asking Outbrain to support WordPress hosted blogs for over a year and nothing’s happened.
I added my request to the long list and soon got a reply from an Outbrain employee:

Hey bangkok photographer – thanks for your comment! I agree with you that this situation is borderline ridiculous. The guys at WP are indeed very nice and we’re very friendly with them, but for some reason it is nearly impossible to get approved by them as a widget for WordPress.com hosted blogs.Our performance is outstanding and we have rarely had any complaints from our tens of thousands of bloggers, so any technical reason would be nothing more than an excuse. I am as mystified as you are by the reason for Outbrain not being approved for WP hosted blogs.
A direct nudge with them would be greatly appreciated. I will try to find out what’s the best way to do that.
Thanks again for your comment here!
My guess is that WordPress are reluctant to support them because they have a plan to do it themselves. But it has been over a year and there’s been no progress.
The Problem With Star Ratings
The problem is that people don’t agree what they mean. In my use of Lightroom I have a policy that pictures get three stars by default.
Five stars are for the best photos I have ever taken.
Four stars are for better than average pictures that I would want to show to others or post on Flickr. I have made Lightroom Smart Collections of family photos, for example, that are four or five star rated.
Two stars are below average but contain something interesting or useful. A one star image is a candidate for deletion unless it contains something unique like the Loch Ness Monster.
I rate every picture and strive for a normal distribution of star ratings with three stars as the mean.
But there are no standards. In Chris Orwig’s Lightroom training he implies that he does not rate all his pictures and only gives them a single star if they are better than average.
So a Chris Orwig one-star might be equivalent to a Bangkok Photographer’s four-star.
Neither of us are right or wrong – it’s our private convention.
So Chris might decline to rate the majority of Picapp pictures he uses and give a star to the ones he likes. Whereas I probably would not use a picture that I think is lower than my three-star rating.
Michael Willems describes his Lightroom rating process here. It has some similarities to mine but he starts at 2-stars.
