Please note that I follow such trends via a specific tag at Delicious.

These one were spotted on the year-end overviews at Springwise:

– Room Sharing with Roomorama

Note that this example concerns paid room sharing:

“”Roomorama aims to provide a quick and easy way to arrange short-term stays by matching hosts who have space to share with travellers planning a visit to their city. Potential hosts begin by listing the details of the room they have, including when it’s available and the per-night price they’d like to be paid. Listing is free, and Roomorama’s search filters and “shoutout” system ensure that hosts see only relevant results. Guests, meanwhile, can either search through the listed accommodations or create a shoutout ad specifying what they’re hoping to find. Once they find something they like, they pay Roomorama via Paypal for their stay, along with an 8 percent transaction fee. In exchange, they get a payment code to be used upon checkin. Only when they’ve checked in and approved the accommodations does the guest give that payment code to the host, thereby releasing the transfer of the funds to the host via check or Paypal. User profiles, feedback history and post-stay reviews on the site create a transparent environment for both hosts and guests.”

– Peer to peer camping:

“Camping, an ancient form of holiday accommodation, is now going peer-to-peer: Single Spot Camping connects anyone who owns a suitably sized piece of land (‘even your garage entrance’, says the site) with those looking for a place to pitch their tent.

Like the more established concept of Couchsurfing, the Swedish startup aims to create travel experiences that are more unique and personal than staying at a regular camping ground. Additional benefits are the small stream of income created for hosts, and the fact that—unlike with couch surfing—both guests and hosts can maintain a sense of privacy.

As the site’s still very new, all listings made before 31 December 2008 will be displayed for a year free of charge. In 2009, listings will cost the landowner EUR 40 per year. Any plots of land sitting empty in Sweden, Norway, Denmark, Finland, Australia or the United States can currently be registered, with the site aiming to become popular with campers and site owners in Europe, North America and Australia.”

– Intention-based shipping:

“,Citizenshipper enables peer-to-peer shipping by matching up people who have something to send with those intending to make a trip in the same direction. Designed for shipping anything ranging from a letter to a fridge, Citizenshipper is free for use by both CitizenSenders and those willing to do the shipping—known on the site as CitizenShippers. CitizenSenders simply post what they need delivered, the starting and destination ZIP codes, and how much they are willing to pay. When a shipper is interested, the CitizenSender receives an email, and can also log in to view the information on their Contract Bids page. CitizenShippers, meanwhile, post the routes they plan on taking, and are notified by e-mail of packages that need to be sent in the same direction. Payments can be handled through PayPal or offline, and Citizenshipper currently charges nothing for facilitating the transaction. The site does, however, incorporate a feedback system to ensure trustworthy participation.”
