Working alone...you're alone. I find that I really missed having someone to bounce ideas off of. It wasn't much easier once I got support staff, because they're focussed on support issues rather than overall business issues (like site content, policies, et cetera).

With two hosting sites in the midst of an overhaul and two other sites getting ready for launch (branded document production/editing and design/development), I sometimes get to the point where I've got so many ideas chasing each other around my head, I can't get any of them committed to pixels.
