With more than 2,000 Internet movers and shakers, the LeWeb conference in Paris is the ideal venue for start-up ventures hoping to attract the investment and attention that could propel them to the next level.

A series of kiosks across the conference arena – a giant arts complex converted from a deserted morgue – saw hordes of fresh-faced entrepreneurs demonstrating gadgets and applications they insisted will change the way we interface with the Internet.

Among these ideas may be the next Facebook or Twitter, or perhaps just a number of spectacular failures. Either way, all will face the same question still being leveled at today’s household names – can they make money?

Some of the more interesting ideas on display at LeWeb include:
ClubCooee – A 3D desktop web messenger program that allows users to create and furnish their own rooms and then host friends to chat and share videos and photos.

TicTacDo – Social productivity tool offering more than 10,000 how-to checklists for doing anything from organizing a party to running for president.

Withings – A wireless bathroom scale that transmits your weight to your handheld device or computer.

Yatedo – “Internet monitoring service” that compiles an online dossier about anyone from all available information on the Internet. Its creators hope corporate customers will pay for this service to ensure that no one is posting unpleasant things about them.

BlueKiwi – Allows companies to create their own secure social network, linking up employees and clients to share ideas and improve efficiency.

PearlTrees – An invention that truly has to be seen to believe. PearlTrees offers a new way of interfacing with the Internet and organizing your online life and friends. It’s either mind-bogglingly complicated or blisteringly simple, but either way it’s an extremely exciting-looking program.

Will any of these ideas be successful? No one knows… yet. The important thing is that we believe in their possibilities.
