Which one of those should I spend my time learning to be able to make cool Web 2.0 apps?

I am trying to design a web 2.0 style logo? Can anyone help me with that?

I am working on a new travel site and need to create web 2.0 icons with gradient. I really liked the icons on some sites like www.yocial.com or www.hieverywhere.com ?

I want to be able to add/delete documents, (mainly PDF’s) allow my users to add documents in a members based service. What is the best way to index these documents as they are uploaded/donated/or already exist in certain folders? Basically I am looking for a program of some sort that allows me to index them into a SQL DB or XML file where I can then write code to allow searching of the indexed information and pull up the correct documents. The basic need is what is the best tool to use to index the content so I have a db to pull from in search queries based on keywords so I can show the most relevant documents to their search text. Is there a program or plug in of somekind that already indexes PDF’s etc and places them into a db or xml format so I can use this info to create my own custom search script/results layout so they can open these docs if they find what they need?
Indexing = file name, file extension, and keywords within the document. I know MS can index the document names which is fine, but if I have a PDF called meridian.pdf, but it is actually for particular part numbers or equipment names or something, I need to know that as well. So I was looking for something that also indexed content within the documents not just the file names.

I am starting a company to build a Web 2.0 application similar to a Discussion Board or Forums. I need help to make sure that the software design is scalable. I have a few programmers in India that can help do the actual coding, but need help to guide them with the design.

I see this as a part-time effort beyond your regular job. I am willing to entertain people with the right skill sets with equity or cash compensation. If you are interested please respond to the question

Please help, this is a bit confusing for me…

Hi there.
I have recently learned about Web 2.0 and how it is revolutionizing the Internet. I am curious, how could I apply these learnings to a B2B environment? For example, how could a company that produces tomatoes use Web 2.0 technologies in an effort to win business from a chain restaurant? Thanks in advance for the help!

This is a pretty darn new engine. It has lots of "hot keys" like that. It’s really a meta engine and I just thought it was interesting. Anyone?

I never had problems with Yahoo’s new Web 2.0 Email Beta. But today, when I tried to login, I get to the "Loading Yahoo! Mail" statement in the center of the browser window, and then it seems to be stuck in some endless loop, as my browser almost immediately becomes unresponsive, and I have to close the program through the Task Manager. Has anyone else experienced this? Does anyone know how to fix it?

I am starting a new website called NetTags, which allows you to make your own social network, and I was wondering what the best date to release it would be. I was thinking New Year’s Day, but I am not sure.
