Benefits Researching with others

I have several family lines that I have researched with cousins.

There are many benefits to research with other family members.

1. Two pairs of eyes on the same research
2. Someone to bounce ideas and information off of
3. One may be researching, while the other is on a genealogy break
4. Someone to brainstorm with
5. Two people to do the leg work. This has been great, especially when we have been in different areas that needed research.
6. Various strengths and interest to draw on

What are some of the benefits of researching with others you have found?
