Absolutely.
I don't believe there can be any better recommendation than personal experience. Constantly hearing about my mate's fabulous travels convinced me to take the plunge, and in the same way there are many blogs here that captivate your imagination. For example, I'd never really thought about going to Antarctica until I read
velvetnron's travelpod. Now it's on my list...
There are a few posters on this forum that are blatantly working in the tourist industry (most of their posts get dumped by the moderators into the Travel Adverts, Deals and Resources section). Their kind of advertising - glowing posts of utopian paradise - has zero effect on me and I'm starting to see it as a thing of the past. Personally, I want a "warts'n'all" description of a place, far removed from the glossy brochures of tourism. I want the real country, dirt and social problems and all. Blogs give me that.
And blogs can not only give you an overview of a country, but sometimes also of individual hotels and hostels there, providing honest and most importantly
current information to us readers planning our trips. Guidebooks are great and all, but yer typical Lonely Planet is going to be at least six months out of date... travelblogs are the way forward!
