the first thing to do is to setup your twitter account, facebook account, myspace, etc. once they are all setup with friends then
log in to http://www.twitterfeed.com
edit or make a new feed
put in the address of the rss feed from your site
under step 2 – add your hellotxt info
once that is setup your wordpress blog is set to send hellotxt.com a message, via twitterfeed.com when you post.
this is a great way to drive some extra traffic to your site, especially when you make decent content that people want to read. combined with a little SEO and a good choice of words then you will see the benefits in a few days to a week.
remeber not to spam post. people will find you and will add you on their own. just make your content interesting and it will happen.
you can also put the hellotxt app on your iphone to stay up to date with all the services =)
one good thing about twitterfeed is that it tracks the clicks fro the different networks, so you can see what tweets / posts perform well =)
