Some churches have wonderful websites, and others have none at all or else ones that are so plain and brief that they're almost useless. These certainly can't make much of an impression on people thinking of finding a church for themselves.
My feeling is that having a good website is important, assuming of course that the congregation really wants to welcome new people. So, it seems a shame that the ones in the second category don't bother even putting together a decent page on a free website.
Then, there are those that look attractive and helpful but, surprisingly, omit some info that I'd consider important, such as the pastor's name, that congregation's affiliation, or a map, or, sometimes, even the address.
