If you use INAP and have noticed oddness with your full-text feeds lately, it may have been caused by INAP. Users that had the “custom options” selected would have their feeds trimmed as if it were a post. INAP 2.4.3 fixes this.
In other news, INAP is in the process of a major overhaul including a complete rewrite of most of its antiquated structure. When this process is complete it will be rebranded to demonstrate the totality of its features (it won’t be called INAP anymore because the name is too restrictive), but will be released as version 3.0
I keep stats though several different methods. Each page and post records its total pageviews, my server keeps its logs, and I use Google Analytics as a backup. Now according to Google Analytics the most popular page on my site has had 13,000 views over a specific time period; however, the page view the page keeps itself recorded over 20,500 in this same time period and the server logs seem to agree.
So while Analytics gives an excellent sample of your data it shouldn’t be relied upon as your main stat source–especially if it is related to ads.
