There are to 2 very popular Wordpress plugins for catch-all content sharing: Sociable and ShareThis. They are both very good. And they each come with their associated pros and cons. Here's a quick look at them in terms of a web designer's blog use.

What Both Have and Don't Have

Together they provide sharing capabilities to the large major sharing services such as Digg, Reddit, StumbleUpon, Delicious, Twitter, etc. They also both provide sharing capability through email and printing. They are also both customizable to some extent. You can choose which services are available to be shared to. Sociable provides 98 services and ShareThis provides 36. Also, noteworthy for designers, neither plugins offer DesignBump as an option.

Individually

Sociable Pros: DesignFloat available DZone available 98 services to choose from logos are easily recognizable Can be included in RSS feed Cons: Larger footprint - Multiple logo images on your posts No FriendFeed

ShareThis Pros: FriendFeed available Small footprint - Just 1 small image Reporting on Click-through (If you register) Post to Blog option Cons: no DesignFloat Only 36 services to choose from.

Overall Conclusion

They're both great. You can't really go wrong with either of them. I tend to favor Sociable more since it includes some designer-specific social sharing sites (DesignFloat and DZine.) At the same time, I very much like the small footprint of ShareThis.

Which one do you use? Why?
