Millions of people use Twitter to broadcast their thoughts in 140-character instalments. But which are worth reading?

Here are 10 tweeters recommended by PC Advisor readers, together with why they're worth following.

1. Jack Schofield

Recommended by: Alexa Ash

Jack Schofield is a massively respected veteran of IT journalism, and offers a knowledgeable perspective on the latest developments in the world of technology. Schofield's tweets tend to include links to longer articles - his own or other noteworthy pieces that he's dug up - but he has a more conversational style when responding to comments by others.

"I tend to rate the tweeters, such as Jack Schofield, who actually engage with their followers," writes Alexa Ash. "I feel like they 'get' the medium."

2. New Scientist

Recommended by: Steve Houghton

Armchair boffins will be familiar with this magazine's trademark offering of fun, novice-friendly science reporting.

Twitter's limit of 140 characters being less than ideal for detailed scientific comment, New Scientist spends many of its tweets linking to long-form content on its main site, but scrolling through the brief summaries on the feed makes for intriguing, brain-engaging reading.

3. Graham Cluley

Recommended by: Steve

"Sophos technology consultant Graham Cluley tweets invaluable warnings on scams, worms and other dangers facing web-connected PC users and smartphone owners," says Steve.

"But it isn't all doom and gloom - Cluley also periodically posts general security tips to help you avoid the perils highlighted on his feed the rest of the time."

4. Jason Snell

Recommended by: Michael J Sheekey

As editor of Macworld in the US, one of our sister publications, Jason Snell is privy to all kinds of Apple-related secrets and insider knowledge.

He doesn't limit his Twitter comments to the Cupertino giant's activities, though - HP's TouchPad tablet was coming in for some robust criticism shortly before we went to press. And, like all the best tweeters, Snell is happy to bandy words with his 17,000-odd followers.

5. Purple Hayz

Recommended by: Zebulon

"I quite like the assortment of tech pointers that Purple Hayz tweets," writes Zebulon.

"There's a good mixture of topicality and links to articles explaining how to do stuff - and not the 'make money from e-books and social media' variety you see so much on Twitter."

Here are 10 of your favourite contributors to Twitter, together with why they're worth following.

6. Stephen Fry

Recommended by: lebeeuk

PCA Recommended Award"One of the best to follow is definitely Stephen Fry," writes lebeeuk. "His tweets are amusing and informative morning, noon and night, no matter where he is. He was tweeting from Israel last week. He's got to be the best there is."

Fry has many, many fans on Twitter, and deservedly so. But we particularly like the way he blends discussions of politics, culture and his own often globetrotting career with fanboyish tweets about technology.

Tune into this hugely popular Twitter feed for thoughts on the latest tech releases by an informed early adopter (among other things).

7. Phillip Schofield

Recommended by: ella33

"When I first started on Twitter, somebody recommended Phillip Schofield to me - partly because his website gives a compehensive overview to Twitter – or in other words a step-by-step guide to using it!" writes ella33.

"I have continued following him because of his light-hearted tweets and comments about reality shows (so it doesn't matter if I have missed something)."

8. Khoi Vinh

Recommended by: Space Goth

Space Goth directed us to Khoi Vinh, "a former design director at and a prolific web-related tech opinionator".

Vinh clearly knows his stuff about digital design, but keeps his tweets accessible to those without a rigorous design background.

9. PC Advisor

Recommended by: Tim Caitlin

Tim Caitlin was kind enough to recommend our own Twitter feed, which we use to flag up articles we're particularly proud of, and to highlight interesting tech news and comment elsewhere on the web. It's also the best place to engage the PCA team in witty banter. Try for our reviews, and for the latest tech news.

10. Microsoft Support

Recommended by: Jim S

Most of the major technology vendors have some kind of Twitter feed; software giant Microsoft, unsurprisingly, has dozens.

This one is our favourite. A dedicated Twitter support team sift through the queries, problems and complaints sent their way and do their best to come up with solutions, tweeting back individual replies to beleagured Microsoft users, or links to longer answers. Much less frustrating than ringing a telephone hotline and being kept on hold.
