The question is how many apps can become one of the coveted 7–10 youuse? No market is static nor is it closed completetly but the ability to crack the top 100 is more difficult today than it was 5 years ago. Maturing markets means closing of some doors. Some areas of mobile are winner take all markets which, for a time being, closes them off.
In your list you have some marketplace apps which is an interesting area since for a long time marketplaces were thought to be a closed market (ebay/amazon) but increaisngly we are seeing new players enter. Remains to be seen if they can succeed long term or will be acquired (e.g. Jet.com).
