You should document all newly added or updated classes. What if you yourself do not remember which classes were added or modified and for what, other scenario is what if your peer wants’ to add similar class how will he come to know which ones are added or modified.. This will spoil your project and lead to  redundant and corrupt code to some level.  Finally managing/maintaining the project in future will be a nightmare.

There is a threashold, quasi-proportional to how many lines of code there are in the project, past which even the original coder is no more able to cope with the "mess". That is why, UML or not UML, if you want to develop anything non-trivial, you need a disciplined approach.

That said, about UML: surely useful for modelling some aspects of a system, OTOH I'd remind Ambler's "Just Barely Good Enough": http://www.agilemodeling.com/essays/barelyGoodEnough.html

In my experience there are a select number of UML diagrams that are quite useful and do help give a visual design of the system.  There are even some fancy tools from the IBM Rational Suite (Rational Rose) that will engineer the code from a well constructed UML diagram.  These tools are expensive and may only be used with larger software teams, but they do have their place if used correctly.  You might be thinking of the "Class Diagram" which I do find useful in explaining the design.  Of coarse with anything there are pros and cons.  I might not get into modeling a system that is a 1 page ASP.NET application with a finite scope; it is not worth the effort with a huge workload to accomplish. There is a ton of buzz on people's opinion as to if UML is useful; take a look at a few of these links to help you shape your own opinion:

Informatics shouldn't be a matter of opinion or buzz, nor you will learn it by reading the blogs, the vendors' sites, and the fake gurus.
