The announcement concerns six new partners and three new features.

In a recent survey, business app advice startup BestVendor asked 550 startup executives and managers which tools they most preferred for a variety of business-related functions.

Teambox, yet another social stream project management tool, has come out with some new enhancements to its service. If you are still using email to collaborate and send documents back and forth, maybe it is time to take a look at what they offer.

This is a crowded market, with tools from Yammer, Basecamp and Socialtext just to name a few. The core difference is that Teambox is both a collaboration tool and task management system integrated into a single tool. The tasks to manage are in line with all the communication and discussions.

Online project management tool LiquidPlanner has come out this week with a complete makeover for its latest v3. The goal was to motivate users to actually have fun while managing their workflows. The company took design elements from Facebook and iOS and redid their entire user interface, adding the ability to drag and drop entire projects to reorder them and easily create to-do lists. You can quickly zoom in to a particular project element to focus exactly on what you care about and create templates to make it easier to get started with new projects. They also came up with a new dashboard and better search algorithms.

Prominent online project management service Basecamp has launched a free mobile web app, built in HTML5 and custom designed for users on a multitude of different handsets. It's attractive, easy to use and hopefully a model that will be followed by 37Signals on its other apps like Backpack.

Loading basecamphq.com on your mobile device will take you to the new version automatically. Makers of the several 3rd party Basecamp mobile apps, who were probably making a fair sum on their software, are unlikely to be pleased. I'm excited to use it though. I really hope it supports Backpack soon.

Basecamp is experimenting with its pricing structure, according to David Heinemeier Hanson of 37signals, the company that created the ever-popular online collaboration app.

Some bloggers and Twitter users noticed yesterday that Basecamp quietly increased its cheapest subscription option from $24 to $49 per month, a move that was criticized by some as as being unfair to small business customers. All other price levels remain unchanged.

We don't usually get very excited when we hear about a new task management service. After all, with Basecamp, Remember the Milk, Todo and numerous other services already in this market, what could really be so interesting about the next new service? It turns out that there is still a lot that can be improved, however. The New York-based team behind Producteev took a close look at the task management services on the market today and distilled everything it learned into the latest version of Producteev.
