I'm typically booted to Lubuntu. As I find myself using AskUbuntu more and more, I find myself further and further from the stock installation. I prefer to give complete answers. I do not want to tell people to install applications that are already installed.
Unfortunately, I don't always remember what came installed and what I have since installed. Let's just say, I've meandered pretty far from the stock installed applications.
I've looked, I've searched, I've used a search engine until I thought I'd tried everything. I may be missing a keyword or something.
How do I find out, fairly easily and quickly, which applications were installed by me? I'd much prefer to use the terminal - I can pipe the output to a text file, if needed and ideally.
Any ideas for things to search for?
Edit:
I am getting a bit closer but it's still a bit of a hodgepodge. Using the advice below and then checking differences I can get most of this. What I am now unable to compile is a list of software installed by means of GDebi that has not ever been updated. And, from the look of my /apps folder, that's a fair number of programs. Not everything needs updating and some don't have automated PPA additions included with them.
I'm actually at a bit of a loss - I'm not sure this is possible. Here I was, hoping for some archaic one-liner in bash that I'd never heard of and now I'm looking at having to write something a bit more complex. Any other ideas?

contains everything you installed, so you've got everything now to answer yourself!
