Please don't tell me this is the future of guidebooks, or, Offbeat Guides part 3: a depressing postcript

Does the world really need travel guides compiled for us from Wikipedia and/or any other online sources for that matter? Following on from my posts on Offbeat Guides part 1: my findings & part 2: my conclusion, I've been thinking about the future of travel guides... but first, the postscript: after posting part 2, I returned to Offbeat Guides for another glance at the Dubai guide to look for some author details. At the end of the Contents, I noticed a References page. I'd initially thought this might have been a further reading list. It wasn't. It turns out the Dubai guide's content came largely from Wikipedia. A few questions immediately sprang to mind:
1) Why on earth would a site marketing itself as a new travel product with its own brand 'Offbeat Guides' rely on using Wikipedia (predominantly) for its content?
2) Why wouldn't they incorporate Wikipedia into their branding? Or announce on the home page where their content is mainly coming from? (Had I have realised that from the start I wouldn't have wasted time testing their beta.)
3) How can they claim they have the most current content on the web when they're so heavily relying on Wikipedia? Not everything on Wikipedia is updated regularly. Content is only as good as the author who has written it. Or the editor editing it! And if we don't know either how can we trust it? Which leads me to my final question...
4) Why did the team behind Offbeat Guides think travellers even needed such a product?

The shelves of most good bookshops are crammed with row after row of quality travel guides written by professional authors, edited by professional editors, and produced by established guidebook publishers (DK, Rough Guides, Footprint, Fodors, Time Out, etc), and then tucked into a little corner here and there will be books in smaller numbers but sometimes produced to even greater standards, like the gorgeous Thames and Hudson Style City guides and the sexy Hip Hotels books, there'll also be a few niche guides like Hedonist's and Pulse's Night+Day series, and there might be a rack of cool guides like Wallpaper's, or a box of Luxe guides on the counter. And we haven't even started on online guides such as Triporati's travel guides and World Travel Guides, and all those excellent resident-authored city blogs that are as good as, if not better than, some published city guides... so why, when there are so many brilliant, high quality, authored guides, do we need something like this? Please don't tell me this is a sign of things to come. If anything, I was hoping that the future of travel guides would lie in more lovingly-crafted almost artisanal guides by small passionate publishers such as Love guides. Please don't tell me I'm wrong. What do you think?
