Just random term.

In my country apple com is #5 and #1 is a blog, wich looks more like autoblog. Next folowed by youtube and next comes classified ads.
This SERP data not means "non of these 3 varinats", because the number monthly searches are 10, the technology is old and nobody have interest to create micro site. This is why the poll is about what You think and not what google results showing.

micro niche sites are a no-no.
Authority sites in any niche are great as long as you go with pillar articles and most of your content is targetted at your linkreators (people with the ability to give you links which are not your main audience)
