Ireland’s Sunday Independent journalist Vinnie O’Dowd has compiled the first ever list of must-follow tweeters who share opinions, news, and advice about Ireland’s most important business stories.

And with Ireland becoming progressively technologically advanced, people have become more likely to flock to Twitter as both producers and consumers of information.

Comscore has estimated that 449,000 Irish people over the age of 15 use Twitter, with about 100,000 people using it daily. Those figures account for a lot of potential customers for businesses struggling to survive the recession.

O’Dowd shortened down the list to our top 10 must-follow Tweeters belows. From young to old, new to longstanding, each of these Twitter accounts are headed by a pro in their field:
