It's a little hard to judge this article when the most important information (the before and after of the name) has been changed in the pursuit of anonymity.
We had a similar experience about a month ago. We rebranded (with help from HN http://news.ycombinator.com/item?id=2560805) from Sfalma (greek word for error) to BugSense and our sigups increased by x4.
I'll go one step further about what you said and guess that a search with a generic English name in a search engine will return 1000s of results with your application at the bottom of page 100.
With a unique name you are now on page one at the top of the results. Probably also valid for search in app stores.
However for this to work you need first to hear the name somewhere and it needs to be easy to remember.
My theory would be that choosing a non-existing word for the name instantly created a brand, whereas before it had just been an anonymous app with a name that referred to what it did.
Hmm this is quite weird. Maybe the new name made it feel more like a 'cool web app' which made more people sign up.
Can't make much of this without the actual name etc though.
From article: "Following our recent article titled -’how i doubled the price of my software product – and sold ten times as many copies‘ we received emails from numerous developers with similar stories to share regarding their own startups, and today we are sharing one of those tales. The developer who’s application we are covering wishes to remain anonymous: please understand that this anonymity is what allows us to share specific user signup, traffic and revenue statistics in these articles that the developers wouldn’t otherwise be comfortable sharing – the anonymity is a worthwhile sacrifice in our opinion- but let us know your thoughts in the comments below. For the purposes of this story, the developer will be known as ‘Steve’ and the product name, ‘Discover’ (at least originally!)."
Is there real value in unknown data?
Is it anonymity or intellectual property, safety or paranoia?
There could be more reasons: probably, or possibly?
