You may notice that today is the one year anniversary of the Scientific American blog network. You may also notice that across the blogs this morning is a shared theme; time for the readers to speak up. Inspired by the blogger Ed Yong, the Sci Am blogs are asking for your thoughts.

Consider this an opportunity to send your message into the great aether of electrons that now perpetually encircles our modest little planet, not unlike sending it out into the cosmic void itself (remember this post?). It’s very easy to register to leave a comment here – if you already use Facebook, Twitter or LinkedIn, or have a Yahoo! or Gmail account it’s merely a click away. That’s so much easier than finding the Higgs boson

Perhaps tell Life, Unbounded and its other readers who you are, your background, and what you do. What’s your interest in science and your involvement with it? How did you come to this blog (through Twitter, Facebook, or sheer blind cosmic luck?), how long have you been reading, what do you think about it, and how could it be improved?

Then let those fingers do some more walking – tell someone else about this blog and in particular, try and choose someone who’s not a scientist but who you think might be interested in the type of stuff found in this blog. Ever had family members or groups of friends who’ve been giving you strange, pitying looks when you try to wax scientific on them? Send ‘em here and let’s see what they say.

Need some nifty Life, Unbounded posts to pass along? Here are some of my favorites:

An Abundance of Exoplanets Changes our Universe

Astrobiology: We Are The Aliens

The Long Hard Road to Mars

You Can’t Always Tell an Exoplanet by its Size

The Molecules that Made the Universe

    I’m Matthew Francis, and I’m also a science writer ( I’ve been reading Life Unbounded since the beginning of SciAm blogs. It’s a great blog for those of us who aren’t experts in planetary science and exoplanet research, but who need or want to keep up with it because it’s good stuff.

    I’m Kevin, a 17 year old HS student. I found “Life, Unbounded” through Twitter. I think it’s informative, well written, and interesting. I value this blog, and the entirety of Scientific American blog network. Whenever I’m dealing with and trying to learn about science, math, etc. concepts, I always return to this site to give myself inspiration to continue. Keep up the good work!

    found your blog via the Sci-Am forum, think you took over for someone else earlier?, can’t recall for sure but have been reading everything you write. Have no formal science education but do possess a burgeoning enthusiasm for all things astronomy and as mentioned above you do a great job of explaining the complicated matters of space so us amateurs can comprehend all the little nuanced details that go into describing our vast universe – the exo-planet stuff are my favorites. If possible for the future I’d like to read about stars similar to our own (in whatever varying stages they appear around the universe) so I can see what to expect from our Sun (not that I have some secret plan to live for a million or so yrs), just curious. Thanks for the great blog!

    I’m a lifelong science nerd (along with several other kinds of nerd), with a special interest in astronomy and biology. Hey, a blog about life, in space. Gee, should I follow this one?

    Yeah, I’ve been here since the great Science Blogs exodus led me to discover Sci-Am blogs existed. I found your blog shortly thereafter and have been enjoying it ever since.

    Thank you, and thanks to all science bloggers, for bringing an endless stream of wonder and amazement to me.

    Thanks for your comments! Great to hear a little of who’s out there, and hope to keep things interesting for you as we get into this 2nd year. The timeline of stars like the Sun is definitely an interesting topic – related as it is to various issues regarding our deep history and of course our future. I look forward to having your readership!

    I am very passionate about the subject of astrobiology and our true place in the cosmos. I hope to one day get a career in the field(or one that revolves around over big and interesting questions).
    I’d love to read an article or people’s opinions about humanity somehow spreading live throughout the universe (e.g. via capsules), if we gather conclusive evidence that we are truly alone. Is it our responsibility to ensure life, and perhaps even conscience, to survive in a somewhat vacant universe?
    I love this blog and hope these engaging articles continue!

    I’m surprised that there are only 7 posts so far–including one in which you respond to a previous post and another that apologizes for grammatical errors in a previous post.

    You are a wonderful writer. I enjoy your posts very much. I don’t remember how I first came across your blog. I was reading it long before you joined SA.

    One possible reason for the paucity of posts is the difficulty of leaving a message. One must either log in or create an account. I tried both unsuccessfully–mainly because I already had an account but didn’t remember that I did. It took at least 10 minutes to straighten it all out. I almost gave up.

    But that’s not your doing. Once again, thanks for your thoughts and the graceful way you express them.
