I just recently purchased a .mac account with the primary goal of putting together a site for my upcoming wedding, and i have found homepage to be extremely limited in terms of what you can do. you have to use their templates, which are fairly specific. once i have time, i probably WILL use them to publish some photo albums and some of my fiancee's written work, but for the wedding site, i have been using the contribute3 trial that comes with .mac. that has been really useful. yesterday one of the guys at the genius bar suggested freeway express as an even better solution, so i'll probably get the free trial of that and go from there.
hope this helps.
there is also a site called dotmac.info that has a lot of useful tips on publishing through .mac
cheers
