I finally started a newsletter! Thanks to all the noise and the stories from other indie hackers, I finally decided to do it. It's called diezlineas (ten lines) and it's a weekly email about tech news IN SPANISH. Here's the link:

Feel free to drop feedback about anything (ideas, design, why you think it will or will not work, etc.)
I went through the responses in the @indiehackers tweet about newsletter stacks
and decided to go with emailoctopus (low price, easy to use, and they did an indie-hackers podcast) and netlify for the landing page (very easy to use so far)
I started sharing the link today, and there have been 18 subscriptions! So fortunately, I won't be emailing just my self :)
