So, I wanted to add tumblr to my Android tablet.
There is a tumblr app for Android. So I searched for tumblr in the Market.
I have hundreds of results. Not one of them is the app whose name I typed exactly. This is because the search does not give any preference to an exact match. So everything that has the word tumblr anywhere in any part of it is an equally good candidate.
This kind of crap is why I don’t consider Android a remotely credible competitor to iOS. The people maintaining the Android ecosystem have given no thought at all to making it even possible to do very simple things like “I want to look for an app with a particular name.”
(Or maybe the app exists but won’t work on this tablet. Who could tell? There’s no way to find out from here.)
