On one hand, it shows that I am active in the community and some things that I have been working on.
On the other hand, it may be distracting on a resume and I am unsure how an employer might view it.
Any advice would be greatly appreciated!
If you provide me links, it also ensures I find the right accounts for you, and not someone with the same name. Finding the wrong accounts and thinking it's you could mean the difference of me actually calling you or not.
StackExchange accounts relevant to the position you're applying for are also good to include (if you use the service).
I am pretty active on Stack Overflow and Github, so I think I'll put those on my resume as well.
If I was hiring a web developer; Yes, it would help to put it on the resume because there may be conflicting account names or save me some effort because I'd check anyway.
In fact, put down hobby projects (eg github) as it will show them that you're also active with source control, delivery, etc.
