I like how easy it was for me to use, very intuitive interface so that even someone inexperienced with this kind of thing can figure it out quickly.
It's great, but sometimes there are addons or plugins you cannot access unless you pay for them because they aren't included in their free version which leaves one feeling stranded without being able to do much else until further updates arrive. I've been using my own domain names instead of third party ones which makes things more secure. Using multiple domains allows us to see what search results we're getting by going to each individually.
