Blogging behemoth b5media has published four more blogs in the past two days.

First is High Def Delight, which talks about –you guessed it — consumer HD. The blog aims to share “developments in the high definition phenomenon, Blu-ray and the merits of investing insane amounts of cash for your living room theater”.

The day after, b5media went trekking around the world with a trio of Travel & Culture blogs:

• The London Traveler — “the sites, history, and current events across the pond”
• The Switzerland Traveler — a blog on the enchanting country in the shadows of the Alps
• The Las Vegas Adventurer — “there’s more to the city than just the Strip”
