NEW YORK (

MainStreet

) -- In these brutal, short digital days, it ain't easy being a "disruptor." Business automation giants such as

Salesforce

(CRM) - Get Report

or

NetSuite

(N)

like to act the role of hunters for say,

Microsoft

(MSFT) - Get Report

or

SAP

(SAP) - Get Report

. But in an age when all it takes to make a great business app is a couple of coders with something to prove, Salesforce and Netsuite are themselves the hunted, challenged to say what they really offer compared with

Rapportive

,

RapidTask

or

Pivotal Tracker

? All of these are cheap, some are free -- and they solve most of business' organizational issues.

To Salesforce's credit, it is not going down without a fight. Several months back, the company rolled out its answer to low- or no-cost business software, Do.com. The free service offers basic task management to anybody with Web access and offers users all the hip, biz-app bells and whistles. It has solid integration with mobile devices such as the iPhone, tries to be a viral alternative to traditional business apps and to give Salesforce a toehold in the fast-moving free business apps world.

For Salesforce.com, faced with a time of terrific competition, it is do or die with Do.com.

Intrigued as to what Do had to offer firms, we have been giving it a test drive for about a month or so.

What you get

Do.com is nice little team task-management tool.

To Salesforce's credit, the company has wisely jettisoned its traditional, complex interface, and Do.com could not be simpler to use. Think of a souped-up version of Basecamp, the fast-growing project management service from Chicago-based

, but absolutely free. Creating an account is a snap. Head to the company Web site -- the impossible-to-forget

do.com

(no "www" is not needed). Create a free account. Then start listing tasks, creating projects and adding notes.

Once your work is broken down into steps, Do.com enables reasonable collaboration. Enter an email for those who work in your team and they get invitations to tasks. Notes, attachment and decent discussions about tasks are supported. Overall, the service was fast and easy to use. The mobile app on my test iPad worked reasonably well.

In general, if your shop is looking for a solid starter productivity tool, Do.com can do the job.

What you don't get

Do.com is not going to solve Salesforce's problem. And it's unlikely many businesses will use it.

What's truly sobering about Do is that despite its solid design and usability, it feels scant compared with other choices. Do.com is actually a yawner by modern project-management and task-management standards. It does most basic task-management tools well. But considering how powerful something like even basic

Google

(GOOG) - Get Report

Apps or a Microsoft spreadsheet is, there is no reason to settle for pretty good. The powerful features in, say,

RapidTask

,

HiTask

,

LiquidPlanner

and dozens of other programs make much of what Do.com mundane.

For basic work, Do can be play a role. But for even modest task management, there are better options.

Bottom line

Do.com is a usable project-management tool any shop can use to get organized. It's fast and simple to use. And if you are not using any sort of tool like it, by all means give it a try. It will work for you. But my sense is that Do.com is not going to amount to much. The competition is just too stiff in the market, and what Do.com offers is not that compelling.

Before you commit to this software, by all means look around. When you are done considering the options, you will probably agree with me that Do.com should have been named "averageonlinebusinesssoftware.com."
