I ran into an article today that talked about this great service/platform.  The idea behind it is creating a place for neighbors to converse, help out, give tips, etc.

The concept of Think Global, Act Local is endorsed by creating a community based on geography that can be a place where neighbors can go when:

• A catastrophe occurs and you want to stay in touch with neighbors (Hurricane Sandy)
• A new restaurant opens and you want to let your neighbors know so the restaurant becomes a success
• You are looking for a dog sitter, baby sitter, house sitter and having someone from the neighborhood often is the best referent
• You want to commiserate with neighbors about something that is going on in your community.

It is free, fun, and potentially fulfilling.  Give Nextdoor a try.
