ooh, some lovely discussion points since yesterday! 
I'm a firm believer in websites too - our churches' (we're a united benfice so we have 2 churches - more on that in a minute!) website went rubbish for a while, when our vicar left (
) and we were left in limbo - we still had a part-time minister, but the diocese were pressuring her to find a full-time job elsewhere (ie if you don't leave we'll stop paying you anyway cos we can't afford it), and part of that limbo meant that the website was left untouched for ages (it's still a bit out of date, but it's being dealt with). Anyway, I got annoyed with the fact that it was out-of-date and wholly unhelpful, so I made a website for our choir. It basically bigs us up, and shows how important the music in the service is (St Augustine said "those who sing pray twice")
We still have the choir website, and are waiting for the churches' website to link us... 
United Benefice- we have two churches in town, St michael's and st mary's. The last Vicar made great moves to make St Mary's "family friend;y" and happy-clappy, and was trying his best to do the same to St Michael's, but eventually conceded that St Michael's would be traiditional and St Mary's Modern. All very well and good, but it seems like we are completely separate churches! We very rarely get new people in St Michael's because St Mary's is aimed specifically at families. Not that it is, and we will welcome anyone, but all school holiday activities are done at St Mary's, all the clubs and groups etc for kids are there, and they have the clapping, music group with guitars and over-head projector, that kind of thing.
We used to have a sunday school at St Michael's, but it dropped off, and more and more families are pushed to St Mary's. (i know they don't intend to do that, but that's what happens!)
the MAIN reason for the problem, as far as i can see, is that the two churches act very differently, and to the publis, they are different places, so there is little or no crossover between the two.
St Mary's has an evening/tea-time service every week and we have the sunday morning 10o'clock service. sometimes St Mary's does lunchtime stuff on a Sunday (like at Harvest), so it all flows nicely, and they always get the evening quiz nights etc.
I truly believe that if we had one building offering all the different stuff at different times, it would be a different story. I reckon there would be a much bigger crossover in congregation, and it would welcome more people.
Unfortunately, because both churches have their own staff, congregants, feel and look, that's not going to happen unless it's forced by the diocese.
I will favour St Michael's being the one to use, because it's got the Organ and the space (it's huge) and the town centre presence(st mary's is hidden in a row of terraces, whereas St Michael's is bang smack on the High Street), and the history.
whereas others favour St Mary's because it's carpetted, has a joined-on church hall, (therefore toilets that you don't have to traipse down the path for!), free-form seating, a better sound system... (no organ, though, and the acoustics are Rotten, which is why it doesn't work for the traditional services, whereas St Michael's can be used for modern services, and can cater for the large number of school children and memorial services' guests.)
