I assumed it was about you anyway.
About normalizing: don't. It achieves nothing. If you want to adjust the level of the vocal (or anything else), just turn it up.
When Greg's talking about getting the vocal to blend in with the rest of the mix, he's talking about putting a reverb or delay on it, which if done right, will make it sound further back in the mix, blending in with everything else. The more reverb you put on it, the more it will blend in. The drier it is, the more it will be upfront. Forgive me if you know this stuff already:
* Don't put the verb/delay on the vocal track as an insert. Set it up on a buss, and set up a Send on the vocal track to the buss.
* Find a verb/delay preset you like the sound of and put it on the buss. (This'll take time. It's like shopping. Actually I like cruising presets better than shopping.) Keep the verb 100% wet on the buss. Leave the level at the default setting.
* Turn the Send level on the vocal track down to 0 and listen to it. Slowly fade up the Send level of the reverb and decide if you like it. If you like it, set it at a modest level so that it isn't obvious.
* Go back to the same verb on the buss and shorten the decay/tail on the verb so that it becomes even *less* obvious.
Now your vocal's more blended in. Tweak to taste.
