It depends upon how easy it is for me. 

Ancestors of course. 

Siblings of my ancestors, yes if I have a record that lists them such as a census. I'm still doing a lot work on one side of the family that has 2nd and 3rd cousins, so I'm actively trying to get out to 3rd cousin.

Step children of a 3rd cousin, yes if in a couple of cases the information I needed to get (cousin's wife's maiden name) the information came from say an obit that included the info.

On the flip side I have a critical source that links two sides of the family. His database is posted on line (including errors). His database has his wife's family and kid's spouses families pretty far back. I didn't include any of his wife's or son or daughter-in-laws ancestors in my database mostly because there were to many.  I have included all the descendents of our common ancestor though and have included a copy of his GEDCOM as part of my sources.

A positive reason to include more people is that you might be able to find other people with more information. At least include your ancestor's siblings. Without my distant cousin including me and my family I'd have never gotten as far back as I have.

I have inherited genealogical works covering three different branches of my family. At first, I thought this was a wonderful boon. But after paying my daughter to enter the names from the two hard copy sources, into a spreadsheet, so that I could later link the people together in their families with Gramps. Then trying to clean up the mess found in the third, which I was able to coerce into the GedCom format. I've begun to wonder if I really need to record all of these people. I now have thousands of people I care little about in my database and, whenever I have a moment, I spend it cleaning up and linking them up to their families.

How far out on the branch of a family tree do hobbyist usually wander?
