Facebook "Networking"

I am a "fan" of several local pages that are either interest-based, such as being a mom, or have some sort of local publication or group.  I follow them to see what is going on around town, as I rarely read the local newspaper.

I saw several local businesses post on the walls of these types of pages promoting their business.  "Need a photographer?  Check out ABC Photography!"  "Best Burgers in town at Big Burger!" Etc.

While I see the opportunity as some free advertising, I don't do it.  Why?  I don't know... there is just something about it that seems a bit "off" to me.  I will gladly self-promote myself if a page is asking for pictures/info from fans, but to just do it to do it... eh... maybe it is just me and my personality.  It's like me at networking events... I usually hang back and chat with whomever I already know or who I am really interested in meeting, not necessarily who I should be talking to because they would get me business or new business.

Along these same lines, I don't go to TV cake designers pages and say, "Check out my work!" in hopes of gaining new fans or recognition from them personally.  Sure I would love to have Kerry Vincent say that I do awesome work, but I don't do anything that at least half of the cake designers in the world do, and I am sure at least half of those designers do those things better than I do.

So what are your thoughts on promoting yourself/business on other Facebook pages?  I am out of my mind and over-thinking things (wouldn't be the first time)?
