What was your hot topic of 2010?

The year is quickly winding down so I wanted to take a moment and invite you to a Twitter chat at 12:30 p.m. Tuesday that I’m hosting.

The chat will focus on the top stories, trends and issues of 2010 and look ahead to what will dominate 2011.

Make sure you are following us – @washtechnology is our Twitter handle. Use the hash tag #WTchat to be part of the discussion. Ask me questions, make comments, argue with me. It’s an opportunity to more directly connect with me and other Washington Technology readers.

Here are some of the topics that make my list for the top stories of 2010.

* Booz Allen Hamilton’s initial public offering. While the Carlyle Group still owns nearly three-quarters of the company, I think we’ll see more activity from the company as the market allows. It’s also a huge cultural shift to go from being a private company to a public one.

* CGI Group acquires Stanley Inc. This deal changed CGI in fundamental ways. It more than doubles its federal government business and more importantly gives CGI a substantial defense and intelligence business.

* GTSI suspension. The Small Business Administration nearly put GTSI out of business for allegedly using small businesses as fronts to funnel money and work to GTSI. Two other companies have been suspended and GTSI’s CEO had to resign to get its suspension lifted. We haven’t heard the last of this one. The question still remains if GTSI can regain its footing, and many people are wondering if SBA is looking at other large businesses as well for similar practices.

* Budget and debt. The full impact of this hasn’t been felt yet, but it is the black cloud looming over the market. Serious cuts are coming, but where and how deep? Who will feel the most impact?

* Procurement reform. The Office of Management and Budget has laid out is 25-step program, which includes a cloud-first philosophy and advocates for more communications between industry and government. It is hard to argue with what OMB wants to do, but the devil will be in the details.

Those are just some quick thoughts on 2010 and 2011. Let’s talk on Tuesday.
