Top 5 Tools for Social Marketing

It seems that social marketing is quickly replacing, or at best, supplementing traditional marketing approaches these days.  I make use of quite a few social marketing angles, but realized I typically stick to 5 tools on a regular basis.
Before you even think that social marketing is the silver bullet in your marketing arsenal, you must first have something “sociable” (not the crackers, although they are yummy) to spread…like a virus, but in a good way.  If you don’t then chances are that social marketing won’t work for you.
So here they are, my top 5 social marketing tools for almost every post I make to the blog:
1) Windows Live Writer- The absolute best blog posting application, surprisingly from Microsoft.  This client allows me to not only post to WordPress blogs, but it will also ping to my super super list of ping servers.  Windows live writer allows you to add/edit/adjust images (which will automatically ftp them the your server) and make use of a ton of third-party pluggins such as suggested images, embed media and other cool things.
2) Pingoat – One of my go-to sites to ping servers that I may have not added to my Windows Live Writer config.  I kind of make it a habit of that when I post something to immediately go over to Pingoat and submit my site.
3) StumbleUpon – I actually use this site to “stumble upon” some cool websites.  It is nice to build up a network of “friends” and let them know about your latest post.  I’ve seen great results with StumbleUpon and they seem to be less “cliquey” than Digg.
4) Feedburner – A great site to manage your rss feeds and makes it easier for other to consume them.  If you don’t think that rss feeds are important, then well, you can go ask Google why they thought it was important enough to incorporate Adsense with it.
5) Twitter – Some think of Twitter as just a place to talk about where you are hanging out, but realistically you have to think of it as a tool to announce socially what you are up to!  Made a change to your website? Wanted to review a new product?  Just a few things to think about for using Twitter as a social marketing tool.
Now, of course you may have a few more items (as do I) but I figured a top 5 post would look better than a top 6 or top 9 social marketing tools post. Seriously, these are the main tools that I use regularly.
