Laura Sorensen — the talented designer behind Atelier LKS (and my first cousin) — explains why Squarespace might not be a great for fit for your website in 10 Reasons to Choose WordPress Over Squarespace.

Some Squarespace sites are gorgeous, but you can bet they have a full stable of high-resolution professional photography to accomplish that, because their templates virtually require it. If you lack professional photography, your Squarespace site could easily look odd or underwhelming.
