Ello is microblogging silo similar to Twitter or Tumblr for posting short status update notes and pictures. Ello offers threaded commenting and a minimalist "designy" feel to it with some unusual (but nice) UX animations & interface ideas. As of Sep. 2014 Ello is currently invite-only.
Ello provides the following features as observed from others use thereof:
- request-invitation & login with a email address, user chosen username, password
- follow and unfollow
- reader UI with an integrated UI to:
- post a note in Markdown at a permalink with:
- profile page (equivalent of indieweb homepage) configuration including
gRegor Morrill inquired about adding microformats2 support or other indieweb technology like webmention. A developer responded that he was not personally familiar with them, but would give it a look. 
Ello has not announced an official API yet, but it appears there is one. Unofficial documentation: https://gist.github.com/conatus/cc665f917d5558c123bc
POSSE to Ello
There doesn't appear to be a way to automatically POSSE to Ello.

- manual POSSE comment - first comment on https://ello.co/cshirky/post/a99yZmd6ZPMwM5Yatk0rRQ
- Ello lacks permalinks for comments
- "reshare" POSSE tweet, automatically generated by Known: https://twitter.com/TapestryMaker/status/518446785413402624
If you initially create a status update on Known, you can add the ello link by clicking on *Reply to a site*. If instead you create a post (in which the headline will be used for the tweet) you'll need to edit your known post to include the link to ello. Here's an example; I put this HTML is at the top of the reply
<div class="reply-text" style="color: rgb(34, 34, 34); font-size: 15px; line-height: 24.6399993896484px; background-color: rgb(255, 255, 255);"> <p style="font-family: Helvetica, Arial, sans-serif; font-size: 1em; line-height: 1.5em !important;"> <span class="icon-reply"></span> Replied to <a href="https://ello.co/womenwhotech/post/08obTue-ISU3v4pGh7szsw" rel="in-reply-to" class="u-in-reply-to">a post on <strong>ello.co</strong> </a> </p> </div>
The following accounts are interesting for their content, commentary, or authorship:
- https://ello.co/waxpancake - example of lots of text, fairly critical of Ello itself
- https://ello.co/thomashawk - beautiful photos, shows off Ello's large photo display in photo posts, e.g. view on a zoomed out window on a cinema display
The following praiseworthy design aspects of Ello are worth noting and further analysis / reverse engineering for indieweb designs.
Fairly Effective Use of Whitespace
Once past the landing page, Ello opts for a completely blank, white canvas upon which their users' content is placed. Individual posts are set off from other posts and page content only by effective use of whitespace, rather than background-colors, lines, or flashy ui.
Large Photo Display
View https://ello.co/thomashawk zoomed out on a cinema display and see how well the photos scale. Though they could perhaps even do better going full bleed with the images. Thomas blogged about this on his own site:
Unsustainable VC Funding
See criticism on this theme written up by Andy Baio on Ello itself:

See above ^^^ (ello.co/username/post/gibberish-line-noise-hex)
- not sure this is really fair, there has been no criticism of twitter on this when it uses only numbers instead of numbers and letters. Ben Roberts 11:57, 12 August 2015 (PDT)
There's no way to link to a comment, e.g. Jon Pincus's first comment here https://ello.co/cshirky/post/a99yZmd6ZPMwM5Yatk0rRQ which he manually POSSE'd from his own site: http://stream.tapestrymaker.net/2014/cshirky-good-points-is-it-possible-to-provide-flow-when
No rel-me support
No Official API
- See API.
No way to export your content / data.

Facebook's statement: "Trust us. We'll show you ads."
App.net's statement: "Trust us. We'll charge you so you don't have to see ads."
Ello's statement: "Trust us, we won't show you ads."
The statement we deserve is akin to email's promise: you don't have to trust us; competing providers keep the ecosystem honest.
Ello seems to add extra things in the history and makes the browser navigation buttons act strangely, at least in Firefox.
Ugly monospaced-font, with small font-size makes it hard to read. Font declaration in Firefox reads "AtlasTypewriterRegular","Andale Mono","Consolas","Lucida Console","Menlo","Luxi Mono",monospace -- Kartik
Errors and Downtime
On 2014-10-03 I noticed the main Ello interface seemed to stop working. Clicking a note permalink or comments icon did nothing. When I tried to view the profile directly, this error message was displayed. The errors did not appear to persist for more than 30 seconds, though. — gRegor Morrill

Ello is a simple, beautiful, and ad-free social network created by a small group of artists and designers. We originally built Ello as a private social network. Over time, so many people wanted to join Ello that we built a public version of Ello for everyone to use. About
