This question has prompted me to pull together a list of BioStars on Twitter:

http://twitter.com/sjcockell/biostars

It's a work in progress, let me know who I've missed...

By extracting the users' pages:

for I in `seq 1 2166`
do
  echo $I
  curl -s "https://www.biostars.org/u/$I" |\
  grep -i twitter  >> file.txt
done

I would recommend to search twitter using #bioinformatics, #genomics or related #tags to follow the relevant tweets and tweeps. You can use the official twitter client TweetDeck to search multiple #tags in a single window.

Hi,

I mostly follow some biologists/bioinformaticians (some of them active on Biostar) with my twitter account. You can have a look at the little number of people I follow there:

Once you have a small basis of people you follow Twitter generally comes with valuable suggestions of new profile to follow (if you use the web interface).

I'm also interested in this thread since I was looking for more worthy people to follow. =)

Franklin Award winners on Twitter:

• Jonathan Eisen
• Alex Bateman
• Ewan Birney
• Michael Eisen

I think another useful way to use twitter is to follow resources, like @OmimOrg, @GenomeBrowser, @yeastgenome, @cytoscape, @galaxyproject, @reactome ...

Here is a curated list to start with: http://twitter.com/#!/dnatimes/bioinformatics-wizards
