The current review system is flawed. You build a wonderful voice platform for users that appreciate voice-first interaction. Why on Earth would you make a user that (may be) wants to leave a review for a skill go through a series of steps that are common for a smartphone app or an actual product but got nothing to do with voice-first experience:
Find phone, open (slow) Alexa app, go to skills, find the skill, type in the review. Or even worse do it from the Amazon's website.
No wonder Dashbot report (https://www.dashbot.io/2018/10/16/alexa-skill-ratings/) shows that 95% of the 40000 skills in the Skill Store have 8 reviews or less and 62% have no reviews at all.
Users want to use voice to do LESS work to SAVE TIME, and current review system is not up to it. It's an extra task that most won't bother doing.
An this flaw totally kills it for both the users (who can't appreciate a lot of skills that never been rated) and the developers whose skills are in a limbo among 26K of other unrated skills.
No wonder many skills (even or especially popular ones) add a "begging" call to a user to leave a review during session completion.
Please add a feature to allow user to rate a skill and leave a review using VOICE only. At least the rate part should be easy to implement.
After a user invoked a skill a couple of times - during session end Amazon should trigger Skill Rating Offer automatically and take control of the dialog. If the user declines to rate - fine, don't offer it again for this skill. But otherwise - many users would actually appreciate an opportunity to rate something immediately after use.
