I know a lot of folks out there use FeedBurner to outsource the hosting and metrics of their RSS feeds. I've not done so (yet?) but am curious about one thing.

If you use FeedBurner, what percentage of your overall subscribers are using Bloglines?

You might think that this is a roundabout way of asking trying to ascertain Bloglines share of the "market" but it's not. I believe there's enough bias in the types of people who even use Bloglines that the number I'm asking for aren't terribly meaningful in getting at their share of the market.

Any, please share if you have such data. I've always assumed (meaning that I pulled this out of my ass) that Bloglines represents between 30% and 50% of my subscribers. But for all I know, I'm way, way off.

Your numbers could help to triangulate a bit. In fact, I suspect they'll help a lot of people wondering the same thing.

Out of 67 subscribers, 9% use Bloglines, 45% use Webmail.us RSS. But I guess my subscribers are biased.

FeedBurner claims that 8% of my feed readers are for Bloglines. I should note that the raw number of Bloglines readers in FeedBurner is different than the Bloglines number of people subscribed to my feed, by 24. Adding the difference to the FeedBurner numbers brings it up to 19%.

I only have one Bloglines subscriber that isn't me. So, probably about 5%.

16.6 percent. No idea why I'm so much lower percentage wise than everyone else.

42% of users for my personal site.

For a site that's strictly a technology podcast which I've got access to, Bloglines subscribers make up 11% (after, obviously, iTunes).

I'd be curious to hear which way you think Bloglines users are biased? I don't disagree, but I'm curious about your opinion on the subject.

Sorry, I don't have a blog - but I am also curious about your thoughts on bloglines user bias... I feel stuck with it because I bounce between 3 different computers regularly (and even more irregularly) and value the access. In a lot of ways it bugs the hell out of me, but I'm not aware of any hosted service that is close (Y! Mail beta is slow and clunky (and feature-poor wrt RSS), though it's more usable than My.Y!).

31%. However, there are a problems with this number. Most notably, it's the absolute count that Bloglines is reporting to FeedBurner. Unfortunately, it's impossible to "cancel" a Bloglines account, so if you are no longer using Bloglines (and using something else), you still show up in the Bloglines number. A few months ago, FeedBurner started reporting a new metric called "Reach" which is the number of people that actually read your feed in the past 24 hours. My "reach" is usually 25% - 30% of total subscribers. FeedBurner is not yet reporting reach by user-agent (e.g. aggregator) - that's coming soon - and will be a much better indicator of "active users" and aggregrator share.

I use FeedBurner and according to it:
Total Sub: 36
Bloglines: 5
Abilon: 11
FeedBlitz: 5
Firefox Bookmarks: 3
Other Aggr/unknown: 12

So around 1/7th of my feed sub use Bloglines... Most other services are pretty popular too

On my Dutch library blog I do have 216 subscribers using my feedburner feed. Of these 124 (57%) use Bloglines. Netvibes has been hot here, and holds second place with 39 (18%) subscribers and FeedReader holds third place with only 9 (4%) subscribers.
Apart from that there are still about 16 bloglines users that don't subscribe through my feedburner feed, but use the atom feed directly. Which make you wonder about the other users that subscribe directly.

# Alex Barnett said:

Hovered between the 20% and 25% mark across two seperate feeds (one has 1,300) the other has 1,000+.

On the first feed, #2 is Netvibes at 18%2% and 34% 'unknown'. Remainder are made of usual suspects.

We don't use Feedburner, but a homegrown feedstats system that is bad in similar ways. Across every feed on WordPress.com, Bloglines is third after Newsgator and Netvibes. Newsgator might be unusually high because of Scoble. Depending on how you count browsers and other junk, Bloglines is between 15-25%.

Across about 5 FeedBurner feeds I find - consistently - it is almost exactly 10%...almost everytime. It's gotten to the point where I use the number of bloglines readers of a feed (lets say 250) to estimate the total readership (i.e. 2500).

# Nicole Simon said:

Usually I find them to be roughly a third of my subscribers, on the english as well as the german blogs. But this probably also has to do with my kind of audience - many use bloglines becuse they have more than one computer and that is the way to share your feeds with that.
