Much the same in my case, except that I never felt tempted by BITE. On the occasions when a google search led me there, I was always disappointed with what I found and decided to ignore it. When another search led me to Pubs Galore I was impressed by the presentation of the information, and, after joining, by the enthusiasm of the admin and the congeniality of the users.
I wouldn't claim to have put Sheffield on the map, but I (and others!) have now got the Sheffield page to the point where there is only one pub without a photo (except for closed pubs that are no longer physically capable of being photographed). I'll try to get a photo of the last one before the year is out.
I'm not going to set myself a similar target for reviews, as too many are bars or night clubs I have no desire to visit, but I'll give the others a go over the next year or so.
Happy days!
