Those hosts may come recommended by Wordpress, but one should keep in mind that with one exception they're all affiliate links, leading you to budget hosts. At the very least, one must keep in mind that $10 will most probably result in $10 worth of allowed CPU usage. Blogs and applications in general can be quite CPU hungry.

Budget hosts can be good while you're starting out, but due to CPU usage, you'll have to upgrade before you get even close to using the allocations they advertise.
