At the moment, I'm limiting myself to these two as options, based on what I've looked at in my own research. They seem to be offering the features I want without excess filler features that I'll never use. My big concern is people's experiences using either of them in terms of reliability, user friendliness, support, etc.
My old site was on Geocities, but that's folding under its Yahoo merger soon (only took them 6-7 years), and I'd like the possibility of more space anyway. Otherwise, I'd likely continue with them because of good experiences in the past.
Currently, my debate is wiki v. traditional website (and I'm making up my own mind there, no advice necessary on that score). Both have pros and cons for the purposes to which I want to put them.
