There’s always a lot of talk about market share for web
browsers, which is picking up again now that Firefox is starting to eat
into Internet Explorer’s huge lead. But there’s been little talk of who is winning
the battle for the eyeballs of RSS consumers. Mainly that’s because reading RSS feeds is
still a niche activity, but who’s to say that 2005 won’t be the breakthrough year for RSS
Reader software? Or it may well be that RSS feeds will be increasingly read on the Web
(e.g. My Yahoo! or Firefox Live
Bookmarks) or in the Email Inbox (if Microsoft finally integrates an RSS Reader into
Outlook). In any of these cases, it’s interesting to start looking at trends for RSS
Readers and which of the current crop has the most market share right now.
I’ll start the ball rolling and offer up my own RSS Reader stats for your perusal. For
the past couple of months I’ve been using Feedburner to track stats for my RSS feeds. The
following graph outlines the RSS Reader spread for people who requested my feeds over a
24-hour period on 17 December 2004.
The first thing you’ll notice is that Bloglines dominates my stats, with over 50% of
my readers (apparently) using Bloglines. However there are a couple of important caveats
I think need to be placed on that. Bloglines is a web-based RSS Aggregator, which gives
it some advantages over the Desktop-based Readers when it comes to stats:
1) Bloglines polls my site more often (on average) than the desktop-based RSS Readers
– which most of the others on my list are. So it’s likely that the desktop-based Readers
are under-represented in my stats. For example, if a NetNewsWire subscriber was offline for a
few days during the 17 Dec 2004 period I used, then his/her Reader would not have
requested my RSS feed during that time – and hence it would not show up in
my stats. I would guess this is a fairly common scenario, as not everybody obsessively
fires up their RSS Reader every day (I’m sad to say I’m one of those obsessives!).
2) Related to the first point, it’s uncertain how many abandoned accounts Bloglines
has that contribute to their readership numbers. With the desktop-based RSS Readers if
someone abandons your feed, that will be reflected in the Feedburner stats because the
RSS Reader no longer requests the feed. But with Bloglines, it’s their server that
requests my feeds – not each individual subscriber. So abandoned Bloglines accounts will not be
reflected in Feedburner’s stats (and there’s not much Feedburner can do about that).
So it’s clear that Bloglines has an unfair advantage when comparing RSS Reader market
share using Feedburner stats. Nevertheless, the gap is so large that it points to Bloglines being the dominant RSS Reader on the Web today. Only probably not by
the margin my stats indicate.
Another thing – my total number of subscribers is around 500, which is pretty good
numbers for an amateur. But it’s probably not good enough to provide a reliable
statistical measure for RSS Reader Market Share. It’d be interesting then to find out the
same kind of stats from some of the professional or big-name blogs using Feedbuner. Boing Boing would be the most interesting and
would provide the best indication of RSS Reader market share. But other professional
players like Steve Rubel or 37Signals would also give a decent picture. Do
you think we can pursuade them and others to share their stats? I’d love to get a more
official view of market share for RSS Readers!
